Mess with annoying blog commentors?

I had a blog commentor that was really obnoxious so I blocked this user's IP address. With the program I use I can send this person to an alternate site. I am looking for a website that will really mess with this person or call this person a jerk or something.





I want something funny or annoying or a little bit mean so this person gets the hint at stops trying to access my site.





Any suggestions?

Rickroll, of course.

I'm sure if you search google, you can find a few that do REALLY annoying things, like opening 5 or 6 windows that jump around the screen. People can get really creative with their rickrolls.
