haha, yeah there are a few other sites like that.
like testmynet.com, testmynet.net, testmy.org (funniest one), testmy.com (like you said).. I'm sure there are more for other mis-spellings. Most people that go there on accident will leave right away so these guys can't be making too much money off it
I don't care about sending them traffic... it's all good
Fuckin' leeches! haha. The testmy.com one actually ranks on alexa ... lol
