[clue-tech] SPAM trap

[Patrick H.]

Not sure exactly what youre doing here. It sounds like you just want to 
keep people off web forms. If thats the case just install a captcha 
check. The only other way is to just keep a manually generated list, 
which is going to be pointless cause there are tons of IPs you'll have 
to block.

If were talking email, use spamhaus's block lists. theyre free and 
reliable. That ip you gave is even on 2 of them.
