That’s fair. But I don’t think the MOBA scene as it is would switch to small communities like that .
Also, for people wanting to cause trouble, bans are meaningless sadly. Unless you also have some rigorous system for sign up. And I guess a small community could have that. But something at scale like a popular game with millions of players can’t.
And rigorous only goes so far, before it’s impinging on privacy.
It’s a tough issue to crack. Popularity and a large scale is always the reason foe all the cheaters and trolls to come around.
