theymos asked this for obvious reasons. What I'm curious about is whether any law enforcement was there behind the decision.
As far as I know, campaigns have broad meanings (many), they are basic guidelines, you can mention support, implementation, activities, propaganda, movements and so on, that's all regardless of whether the campaign acts as fraud, fake, legal or illegal.
I quoted one of the laws that apply to my country, maybe international.
Any person with the intent to advertise a company online to unlawfully benefit himself or others by using a false name or false prestige: by means of deception, or a series of lies, to incite another person to hand over something to him, or to give a debt or write off a receivable, is threatened, for fraud, with imprisonment.
Note: the above quote points to individuals/companies, marketing or freelance advertising that are not legal for them.
In my opinion, this Forum is an intermediary, marketing, web which is basically just advertisers, not actors/campaign owners, logically, if you look at the quote above, it can be concluded, if there are problems at a later date with the campaign, the forum is not involved hands off, it is the company that bears the risk, the bottom line: no one knows what will happen in the future to the companies that advertise themselves in this forum, whether later there is embezzlement, fraud, fakes and so on, the forum is not responsible for that.
The proof:
It can be seen from several gambling campaigns that act as fraud, they are still here, even though law enforcement agencies have made outside efforts against the company.
My understanding, if one of the campaigns or companies that advertise on the forum, the forum has no right to close down the company, if so who has the right, namely: relevant international/electronic authorities, informatics law authorities can act to block fraudulent/fake websites, based on the evidence that has been gathered.
