You're being obtuse for no apparent reason, it is clearly not "because of who they vote for" that they are targeted, but because they are extracting rewards, it doesn't matter if it's a circle jerk as in a group or if it's one individual that is doing it, and it doesn't matter if it's referred to as circle voting or "a group of people providing excessive rewards for each other" because they both mean exactly the same thing.
