For every person your gang helps it hurts many others.
The larger you grow the more your advantage in the math harms others.
Ganging up to influence rewards disadvantages everybody that doesnt play along.
All that 'help' you are giving your favorites comes out of the rewards of everybody else.

If you get ten people in your gang, and they all vote one person, that one person is helped.
9 people get nothing (only what curation they have coming) and everybody with less sp than the gang's cumulative total gets their rewards diminished.
