Blogs Canada suggests an interesting way to use the Patriot Act against blog comment spam:

Dear System Administrator,

One of your clients is defacing my website. It appears they are using an automated instrument to place ads on my site without my permission. This is hacking and that contravenes the USA PATRIOT ACT. Now that you have been informed, should they continue, you are culpable and I will report you to the FBI.

These defacements appear to originate from multiple IP’s, indicating the use of a backdoor zombie technique. That constitutes an even greater contravention of the Patriot Act. The use of trojan backdoors on zombie computers to hide one’s identity while breaking into servers is a technique used by TERRORISTS.

They are violating CAN-SPAM. Again, now you know. You are equally responsible.

It is well known that virtually all sites that promote online gambling are run by the RUSSIAN MOB. The US Treasury Department and the FBI will be very interested in who’s doing what on your servers.

I have pasted a copy of the illegal material that your client used to deface my website below.

Please take immediate action or face investigation and prosecution by the appropriate law enforcement agencies.

Regards,
Sean McLadidahNow, they’ve gotta be pretty prolific for me to be inclined to actually look up the host, etc. But I may use this tactic to go after the bastards who keep port scanning me.
