I think it's a big ego boost for bullies to have a feeling of being superior and more powerful than others without any regard to what destruction they are doing to the platform and either those coming on board or those who decide to throw in the towel after working really hard and long on their work just to see it buried and earning nothing.

I agree entirely with you regarding "policing" and the stalking manner in which they proceed and taunt.

Yes, they are too big to mess with and unfortunately those with the power to do so don't put them in their place. There are too many times here and elsewhere that there aren't any consequences to bad behavior when you have a lot of money.
