If you're letting a random person on the internet destroy your mental health, isn't that a little bit on you? What about this person bothers you so much that he ruins your whole day?
From my perspective, @Mr_F3 is a ridiculous contrarian with a strange sense of humor, but that's not worth having a miserable day over. It also looks like, to me, that you're randomly attacking this guy for no reason. Being a contrarian is not against the rules.
@Mr_F3 doesn't have to listen to what @Jessie_Dearsnap says necessarily - she's not a moderator.
If @Mr_F3 puts too many quotes in his posts, that will be up to @Peregrine_Appleclock to decide whether or not to punish him. It's not your fight or thing to mess with. You're not a moderator, either, and as long as @Mr_F3 is not breaking any rules, he is allowed to exist in this public space.
