and if I should advise you, I will say that you create this thread using your main signature banned account since that signature banned don't limit your posting in the forum, there is no need to create a new account for that purpose.
In addition to the account getting a signature ban for 1 year, I think the account also gets a ban for a certain period of time, it could be 7-30 days. After the ban period is over, he can be active again on the forum without a signature.
I saw several accounts in the same campaign as OP, there were about 5 other accounts that got the same ban. Some in the Stake campaign seemed to have happened too. But only OP made the thread, some others might have given up.
