TOS rules apply to all posters. Moderators are not expected to post any differently than anyone else, within TOS. I have encountered very few "rogue" moderators, and Admin addresses them when alerted.
There's a Report TOS to alert Admin to possible post violations. There's Request Review option to alert Admin to possibly wrongly deleted posts.
Perhaps you'd prefer different TOS rules? Personally, I would prefer a few more cuss words be restricted. But I don't make the rules, so I do not delete those posts, even though I might like to.
