I have been banned for 1 month and it says "banned by Btalk moderator" in Bitcointalk UID field. Now my ban is over. What can i do for rejoin to the campaign?
You cannot rejoin with this member name. Your only options are to create another account and get it up to member status, or buy an account. I'm not sure if you will have to create a new Yobit account as well, (and I think this is frowned upon by Yobit.)
The best solution is to join another compaign and to avoid the same mistake that banned you by h&co
