There is no publicly listed ban list. There's a
modlog that list the latest activities but It's not publicly monitored by the forum.
Just make sure that you don't do something over the top with the account like too much spamming and you won't receive a ban.
All bans listed in "Deletion log" are permanent bans. So it won't work for OP. There is a chance that Admin undo ban after appealing, it can be found by searching because theses days, appeals are done by posting in Meta.
Oh, Sincerely thanks. I think that your way is very good to know a certain account banned . However, almost when buying an account , we do not know
what is its username ? Seller usually don't reveal it to us. So we can't check that account's post history.
Use an escrow who will check quality of posts of the account you are buying.
P.S.
Most seller will not reveal the username of the account, this will be like hitting for jackpot in search of an account with good post history, best thing you can do is to buy account from some reputed member like quickseller, although there will still be no guarantee to that
Quickseller and ACCTseller stopped their account sale.
