Platform owners are allowed to moderate as they see fit. A problem arises however when group A is circumventing the rules and group B is the only group that ever is held to account for the same actions.
A grat example of this is the Steam discussion forums. That is a video game distribution platform, including many competitive online games against other players. One would think it would be of the business's interest to counter things like video game cheating. However Steam has a policy against Naming and Shaming that also applies to cheating. Now, when someone makes a thread about cheating there, it's against Steam terms to post evidence of cheating and users will have their posts removed or possibly be banned. That is why the OP of those threads are always baited into showing proof "or it didn't happen". This oddly enough extends to pointing out that a Steam account is only being used to troll the Steam forums and has no activity other than that. So you see, the rules are actually benefitting those who are not using the services for what they are intended.
As to video game cheating, I didn't start the thread about that, but well, the government doesn't give a shit about that. (EDIT: I noted this is the Euro thread which I forgot when I wrote this, I'm mostly complaining about the rotten US security sector but I'm sure it's applicable in other places as well though I will leave that to the reader to determine) I'll also note they are incompetent and can't defend against cyber intrusions because of the swiss cheese they've made to bypass Constitutional requirements, they oppose reforms that aren't a power grab for themselves and their political extrapartisan faction which doesn't make it much of a reform and more of an entrenchment, and make opponents of the government through leading it astray in their own interests. Why would we expect them to realize the links between black market video game cheating revenue streams and various groups they claim to oppose? It's apparently below their paygrade. It's also international but doesn't have anything to do with green energy manufacturing so doesn't get fucked with through bad advice to sequestered old people.
