Uh. I'm a mod on another VB forum...and the answer is no.
A mod really can't do anything like that...unless they have admin permissions. Which on this forum, I don't think they do.
Now if they had admin permissions, they can ban you, themselves, and everyone else for that matter, and then delete themselves along with the entire forum, if they have full admin.
There is away to give partial admin to some of the users to prevent this.
