I do not recall why your other account was suspended. However, I'm sure there was a very valid reason for doing so (I do not make a habit of banning people for no reason).
As long as you contribute to the forum in a positive way, there shouldn't be any problems.
My advice would be to take a few seconds to review your post before you submit it. I would advise against using bad language, hotlinking other site's images or posting massive amount of unwarranted messages that don't contribute to the thread or forum. My guess is that the combination of those things over a period of time (and most likely after warnings from moderators) led to your other account being suspended.
I want you to have a good time while you're on the site. I also want the site to be enjoyable for everyone else. As long as that's the case, you have nothing to worry about.
