So, you are asking for a good way to break the terms of use and “be nice” policy and get kicked out?
It would be too mature to simply delete the app and move on?
Did the moderator knock you down and hurt your feelings and cause you emotional distress?
Now you want to go out with style and offend everyone who reads your vulgarities and obscenities?
Maybe you offered up a bad answer or said the wrong thing, I do it all the time, in fact—-Quora Moderators have got me on their DO NOT FLY LIST right now !
Take a breather and then return when you want, it's just an app. It's not a job and you don't have to do it.
If you're a troll however, you should be banned from the entire internet if that was even
