Sometimes I wonder, with the exception of a few BLP issues, can one really be "abused" on Wikipedia the same way they can be abused in real life[1]? After all, it's just an Internet website and not even a social networking one. If you can't have your way here then pick up your ball and go play elsewhere.
This is one of the reasons I left the anti spam newsgroups. As much as I hate spam, when it comes right down to it, it's just email.
