If you register using a string of characters that resemble a spam user name or address or I get a postitive ID for those names on a spam list or I find that your email address has been placing lots of inane comments on unrelated websites, YOUR ACCOUNT WILL BE DELETED.
Also if you do not enable your account within a reasonable amount of time I will also take that as a sign that you are not a genuine member and your account also will be DELETED.
If I have deleted your account in error, well, I'm sorry. Just re-register, and perhaps use a better Name (eg: not gruioturieot or some random string of characters). If I delete you again send me an email explaining that your name really is gruioturieot and you've been cursing your parents alternative naming strategy ever since you were old enough to realise how stupid it was).
