Has anyone else used this site? It's helpful if you want to see which freaks that you've deleted off your contact list still have you on their lists... Just thought I'd the word. But I'm pretty sure that this may be a well-known site by now? There are also a couple of other pretty cool MSNmessenger-related tools... all engineered to help you figure out who could be spying on you or to help you do the spying, lol!

ya you can even send a anonymous msg to someone from that site.. has a bunch of fun little tricks on it... i dont know if that msg actually gets sent tho,, only tried it once

its a very inaccurate site, their results of people who deleted you don't always add up.. especially when u know some people wouldn't delete u.. so its just bugs on the websites end.. block checker is kinda useless too
