Are you in favor of electing Moderators?

I don't understand what "check" means.

because our moderation decisions have not yet been questioned by other users

And is it difficult to question something that doesn't exist?
To avoid making unsubstantiated claims, I will give one example:
/post/571246/
Until I pointed out those obvious violations, no one even bothered to delete or edit them. And there were moderators at the time.
And this is just profanity, which cannot be interpreted in any way but literally. There are still posts with provocations (trolling) against Tox in the thread (who, due to his explosive nature, reacts very strongly).
