Disrupting gameplay (?)

Hi!
I noticed that someone recently got banned for 2 days for "disrupting gameplay". Then I started thinking; "What counts as disrupting gameplay?"
In a way isn't camping players in an open world disrupting gameplay? Or perhaps standing in Thrallmar as an alliance player killing the npcs.
I'd really want to know what counts as "Disrupting gameplay" to be banned for.

Standing afk in dungeon or ask for kick to avoid deserter debuff is disrupting gameplay.

Usually it's refusing to play after you accept the dungeon que pop. Idea is that you should have declined or leave the party if you do not want to play.

Also there are probably other things, my general idea of it is "when players can't do anything about it". But camping some NPC or players will never get you banned, if the enemy faction wanted to they can come and protect their cities, it's an intended part of the game.

Well this makes more sense now, thank you.
I was just confused for the reason itself, hence in a way one is disrupting everyone else's gameplay through killing players/npcs.
But all good!
