We normally don't set Auto-Unsuspension. This just allows people to violate the TOS without having to face the punishment ...Now, if you were talking about the Double Everything + Inactivity Timer, that is something completely different and is a paid feature.
The ability to pay for your account to be unsuspended by x10 credits has been removed. It wasnt an auto unsuspension it was a if you had enough credits you could bail yourself out.
Now you just need to post using the request unsuspension form off the x10 menu.
