I was invited to join yobit's signature campaign program, but I was not eligible to participate. I see that they set the rule of maximum 20 post / day, if there are about 1,000 people participating in this campaign, the forum will have to suffer 20,000 spam messages every day. What is the measure for this?
They finally hired a good campaign manager to control the major spam. His job is to check what the users are doing and ban these that are abusing the system to f*ck the forum and earn while doing it.
His list of banned users:
