Damn - DDave beat me to it
Here's the link to the register page that you clicked "agree" on before you signed up:
http://www.greenguysboard.com/board/register.php
Log out before you click on the link, because if you're already logged in, it will not display.
And you sig file was not deleted, it was just turned off - if you went to your profile, you'd see that.
PS - I don't think your a "spammer" as most of them don't even notice that their sig files are turned off
