Now, the mod abuse part is all about your perspective.
Long ago I did a vote on whether or not I should change MSmg's system, where (this was before the owner limit) there would be 3-5 owners, and 4-8 mods that would watch over the stream. The owners were the ones that would control the bans (which includes deciding together what a reasonable ban time was, depending on which rule was broken and to what severity, which at least 2 owners would have to agree on the final ban decision), make big decisions on how to change the stream, etc. The moderators would make reports to the owners if someone was breaking the rules, and delete comments and remove posts breaking the rules. The vote was almost completely unanimous, as nearly everyone who voted had agreed to implement the system.
