In the past year the amount of spam I have been receiving at one particular e-mail address has increased dramatically.
I believe that I have traced the origin of the spam to the public WHOIS domain name registration directory where my e-mail address was listed in my contact information.
I went so far as to trash the e-mail address yesterday, only to begin receiving similar spam on another address used for domain registration purposes. I wish that I had know about this problem before I had registered the domains!
Assuming that I must provide a valid e-mail address when registering, I am considering using the services of this company http://www.alternativeidentity.com/ The service was recommended by directNIC.
Any comments about the information on WHOIS? Has anyone had experience with AlternativeIdentity.com? I figure that there must be more experienced webmasters on TS who have struggled with this problem...
-
I maintain about two dozen Web sites, and my email address is in the whois information for all of them. I report all the spam I get to SpamCop and take other actions against spammers, so even though I'm flooded with spam, I generally manage to get the spammers shut down.
Many people are beginning to "corrupt" the email address that appears in the whois directory, by, for example, listing their email address as "fred@whateverdomain.com#0" or "fred@whateverdomain.com.nospam.invalid". Adding this junk to the end of the email address confuses spam harvesters.
-
I also report spam via Spamcop, but the spam is never-ending and I wonder how much good the spam reports are doing. It seems like more and more spam is coming from ISPs that are overseas, and in some cases I report spam from the same sender/ISP mulitiple times without success.
I think that it is important that people know ahead of time that posting an e-mail address at WHOIS is basically an invitation to spammers. if I had known what I know now, I would have either not provided an e-mail address or I would have monkeyed with the address like you mentioned.

Hi Mayo,
The registrar you went through the register your domains should allow you to modify your information. You could go in (a control panel they've provide maybe?) and make the changes to your email that Tacit has suggested. It won't help those creeps who've already harvested it, but it may stop it from getting out even more.
see ya,
-
Diana, I think I will do just that. It is quite simple to access my account at directNIC.
-
Hmmmm...I just tried to alter the info at directNIC and it would not accept an "inavlid" e-mail address.
-
May not help in this case. But I've heard of people using at instead of @.
People can figure it out but the spambots don't.
-
Hi again Mayo,
You should be able do something like this:
yourid.nospam@valid.dom.com, nospam-yourid@ or something similar
They probably have a script that checks to see if the domain itself is valid, so instead of changing that part, just add the obfuscation to what's in front of the @ sign.
-
Strangely enough (knock on wood) I have never received a single piece of spam addressed to my WHOIS contact email.
I don't know why thas is and no, I'm not complaining, but I think there may be more to it than simple harvesting of ALL contact addresses.
Diana, I'm wondering if modifying the user ID is adequate. Many hosting services include a catch-all mailbox for any misspelled user IDs, so I think that even these modified addresses would arrive in the domains mailserver.
-
Hi kps,
You're right...in fact that is a setting that can be enabled on my server. I try to teach people about the dangers of using that catch-all and since I allow an unlimited number of aliases, they can create aliases for probably mis-spellings. But, even with a catch-all set, you can then create a filter in your email program that will trash anything sent to the obscured email you used at the registrar...unless the message was from the registrar itself.
oh, the work we'll go to to fight the spammers when we shouldn't have to at all. I hope everyone realizes that buying even one thing from a spammer just encourages them all to keep trying. If a spammer sends me something that I might actually want...I'll do hours of research if necessary to find that product through a search engine just so I don't buy it from a known spammer.
*grin...funny story here. I had a phone call. A guy/man/kid asked for me but mispronounced my name..(sure sign of a telemarketer). Then asked if I was aware of a program for keeping a computer safe and problem free. Before I could say anything, he mentioned Norton System works. I immediately butted in and asked him.."are you the people who are constantly spamming me?" A couple of stutters and "uhs" were all I got before the telemarketer abruptly hung up...and me in a mood to "play" with him.

That's so true.
That's a good tip about setting up a filter for the modified WHOIS contact address if catch-all is enabled.

Changing the information in front of the "@" was also rejected. I'm corresponding with directNIC about this issue and I will report back if I hear anything substantive from them.
I think that I will use the AlternativeIdentity service just because having all my contact info publicly available doesn't exactly make me happy. directNIC informed me today that AI is affiliated with them; both outfits have the same owners.
Speaking of stories...Some years back when I was subscribed to a Eudora mailing list we were spammed by an outfit offering one of those CDs with millions of e-mail addresses. Naturally, there was some discussion about the spam on the list.
Then along came an e-mail from a list member to the spammer showing interest in the CD. Apparently the list member had mistakenly replied to the list instead of to the spammer. It just goes to show that even people who should know better respond to spam, which is why it exists.

I have a really tough time with spam, because of the nature of my website. I invite readers to send me e-mail with questions they may have for a psychiatrist. Do I have to tell you, some of the legitimate e-mail I get sounds like spam. For example, Subject: "Sex problem" vs. "Sex Problem?"
The latter is probably another pitch for Viagra.
It's hard tellin' not knowin' (who said that?) So I just open everything. With a little bit of luck, as Diana points out, my computer has not yet caught fire.

Hi Lorraine..
I went to your web site out of curiosity and noted the your e-mail address is not clickable. I'm assuming you have it that way on purpose, but it won't stop the spam harvesters.
Read this link for some ideas for obscuring your e-mail address on a web site:
Anti-Spam Measures
I don't think you can use those methods to protect your book order address, but the questions one can be well guarded from the spammers.
HTH,

Thanks, Diana -- I went to the Anti-Spam link, but it is a little too confusing for me. I am not familiar with javascript, and such as that -- I was not sure which I should choose from his menu of options. I didn't want to paste something into my website incorrectly that would screw things up.
You were right, I added the "no charge for e-mail" at the end of the e-mail address in order to thwart spammers. It seemed to help -- I have not gotten nearly as much spam as I used to. At least it seems that way, I haven't actually recorded any numbers.
I'll take away the "no charge" comment, because I thought it was stupid anyway. How could anyone charge for a question someone asked over e-mail? I'll see if I get more spam when I take it away.
If you know of one of TW's scripts that I should choose, please advise!! Thanks again,
Lorraine

Lorraine, I've had an email address listed on the 4 web sites for which I am webmaster (one of which generates about 600 hits a week, from all over) for over a year and have never had any spam because of it. I simply use the ASCII characters in place of the "@" symbol - it seems to work very well. The only problem I have with it is that occasionally it gets mucked up (copying it or something seems to change it) and I have to fix it. Anyway - the characters to use are: "&","#","64",";" - taking out all the quotes and commas. Just put them where you'd normally have the "@" in your email addy in the HTML source code.
The scripts which change your email address into something like this (only usually much longer) are based on the same principal. While in theory, a spam bot could be taught to interpret the ASCII characters too, I think spammers don't need to bother - they get quite enough addresses simply sending the bots out looking for the ampersands!
-
Thanks, Paddy, & others.
I went back and removed the (no charge for e-mail questions) after my e-mail address, and in the last 2 days I have gotten more than 2 dozen spam mailings! So apparently it was helping.
Paddy, I am not sure I understand how I should change my e-mail address, with the "&" etc. Do I put any of those in the html coding in place of the @? In other words, it would look like "Question & DearDrRoth.com" (without the quotes & spaces, of course)?
-
Hi Lorraine - yes, you simply substitute the 5 characters (counting the 6 and the 4 as distinct characters) in the HTML for the "@" - the reason I can't do it here and show you *exactly* what it is supposed to look like is that it will turn into an ampersand! What you see on the web page is the same - it's the coding that is different.
So what you will have in the HTML is something like this:
<a href="mailto:Question"&"#"64";"DearDrRoth.com">Question</a...
- taking out the quotes, of course, and assuming that the link one is supposed to click is "Question".
Here is a link to a page which describes various options, including the one I've attempted to show:
http://www.netmechanic.com/news/vol4/design_no21.htm
Hope that helps.

Well, the "@" didn't seem to take, for some reason... not sure I entered it properly, although I thought I understood your directions, Paddy.
I visited the link you included and used the javascript for e-mail, and it seems to be working just fine. Hopefully, I won't have any more spam at that address -- just the desired questions from people with emotional problems without the profit motive!
Thanks again so much, to everyone who helped here.

I had no idea that my post would stimulate this very informative discussion; I am going to learn more about the techniques suggested for preventing spiders from harvesting e-mail addresses.
I decided to sign-up with Alternative Identity. My WHOIS information has been changed and I am happy to not have my personal information available for all to see...
