Because of the recent spam issues, I had to banninate a few users who looked suspect to me. If I threw any baby out with the bathwater, let me know and I will grant you a pardon with my apologies.
On that topic, yes you can be banned. No, it's not likely to happen unless you're really over the top. By our standards. So don't worry about it too much.
I'll post specific forum rules at some point, but you know... common sense. Polite society. That sort of thing.
