Make Email Harvesters Choke With This Code
If you want to know what really makes Doug mad, I'll tell you. (Well, besides me and J.D. eating all the chocolate cake before he gets a chance to have any...that makes him REALLY mad!)No, what really bugs him is spam. That's why he has an Anti-Spam Website. And on that site he talks about email harvesters. An email harvester is a web bot that scans the internet looking for email addresses posted on web pages. Once the bot has the addresses, a spammer can use them to mass market to unsuspecting consumers (you, me, and any old dodo out there).
Isn't that annoying? On Doug's Anti-Spam Website, there is a page that randomly generates garbage email addresses for email harvesters to choke on. And the page creates new addresses every time it is loaded, which means every time the spam bot returns, it gets bogged down with another hundred fake email addresses.
Do you want the code needed to add this functionality to your own site? It's right here:
|
Dim strEmail Dim I,J,K randomize timer For J = 1 to 100 strEmail="" K = int(rnd * 5) + 5 For I = 1 to K strEmail =strEmail & chr(int(rnd * 26) + 65) next stremail=stremail & "@" K = int(rnd * 5) + 8 For I = 1 to K strEmail =strEmail & chr(int(rnd * 26) + 65) next stremail=stremail & ".com" stremail=lcase(stremail) Response.Write("<a href=""mailto:" & strEmail & """>" & strEmail & "</a> ") next |
Of course, you need to be running this inside an ASP page, and the code has to be enclosed in the server code markers: "<%" and "%>".
You can change the number of addresses by modifying the line that says "For I = 1 to 100". Just put a bigger or smaller number in there, but keep in mind that the more addresses you do, the more server resources you're using up!
Here's the output of this code, modified to do 20 email addresses:
