You are not baned for campaigns you are banned from the forum. This includes all your accounts.
Obviosly I am banned from the forums, but it says for sig ad. But why?
Also some random guy gave me negative for Sig Campaigns. It's on this account
It means your posts were not up to par with content, and they gave you a temp ban. Can you link to account we might be able to tell more seeing posts?
Best advice is make sure not to try to game system. Treat this seriously and do not use any other accounts to post in anywhere besides meta until ban is gone. To many try to get back quick and get evading and perma ban.
I said this... and I guess op did not read and is posting outside of meta in "Economy / Services" multiple times. Seriously that is most likely a perma ban. And that is for ALL of your accounts. Not just the one.
I tried to warn you as far to often people seem to try to hurry it and not wait... it always ends up bad when they do.
