From what I read awhile back when I first joined, is that the more rep points you have the more potential banning power you have. You can petition to have someone banned who has less rep points then you to the mods...not sure if this is true or not, could be a stupid post I read that I should have red repped them, or even myself for believing it lol.
You are correct in your assumption. Has absolutely nothing to do with getting banned.
