There's a troll on my site who I've banned. I went so far as to ban his IP address. Now, he's coming back through a proxy and making death threats, all kinds of racist remarks, and doing other things to aggressively spam my site and damage my business. He doesn't stop. Probably 10 new accounts created nightly without fail. How would you suggest dealing with him here? Anything I can do to render his proxy ineffective? Any ideas for a page to redirect him to that may scare him enough to never come back again? Any suggestions are appreciated .
