Would you rather have no campaign manager handling YoBit, or perhaps one of YoBit's own staff managing the campaign?
I would rather they have no manager, or a very poor manager.
The above would mean a few days of spam, followed by YoBit having their signatures blacklisted and being unable to advertise. It would also mean a bunch of spammers would get banned.
The status quo means that a shady business can advertise and many people with questionable ethics and profiting from advertising a company that is reasonably a scammer with impunity.
