In the last 24 hours, I've received a flood of over 150 comment spams from the same IP address:
This IP appears to be coming from somewhere in Russia. All the spams were advertisements for various prescription drugs. I have banned this IP address from my web site. Whomever this spammer is, he's obviously an amateur at this. He sent ALL the spams from the same IP address, making it very easy for me to lock him out for good. Plus, while, I do allow comments to be placed on my site without registering, they are not actually shown until I approve them. This means that this guy's efforts have been wasted. His advertisements never showed up on my site. Because of the easy pattern to his comments, it was also very easy for me to go in and delete all his spams in one shot. (SQL is a very useful thing!)
Nice try buddy. Better luck next time...
