Even Legendary members will be banned for spamming. You're lucky that you still have another account that is unbanned. There is almost no chance for that account to be unbanned. Use your current account, don't spam and it'll be fine.
This is simply not true, I remember a guy from the altcoin section who was really butthurt for having his topics removed by mods and he literally flooded the altcoin section with 1000 spam topics bashing the mods and staff, his name was spotnik I believe with hero status and he is still posting today
All I'm saying is I would atleast want to get checked and see if I can get the acc back
