Is there a difference? I don't know. We generally refer to account suspensions, but a suspension can be forever. So to me it's just semantics.

I wouldn't worry about it. We don't suspend accounts without a reason. And we don't talk about the reasons except in private, but it's generally because the member violated the community guidelines multiple times and didn't seem to try to resolve their behaviors to be consistent with the guidelines. A member can also ask to take a break from the forum for a month or more at a time and ask us to suspend their account while they're on that break (we only do this at the request of the member, and it must be for 30 days or more).
