I can only assume that all the different users view the stake differently here. But the ACTUAL reality, beyond all the "shoulds" and "supposed to's" is your stake is just that, yours. You have either bought or earned a portion of the reward pool to do with, whatever you like. Including flagging, so if someone is doing something you don't like, you can flag them. If someone is too big for your flag to matter, then how is this any different from the rest of reality.
The government does stuff I don't like all the time, they're too big for me to flag.
Corporations do things I don't like all the time, they're too big for me to flag.
All the billionaires(whales) in the world could all pool their money together, and probably solve every global problem ever, but I wouldn't hold my breath, more than likely they're going to use their money to make more money, which at our own level is what each of us is trying to do.
Everyone's stake is there own and the rest is lip service.
There is no "Reward Pool Rape" It is simply people using their stake.
Any user can flag or upvote at will. (There might be consequences)
The code is law. The rest is human reaction.
