Alright, so if Bulborb was the one handing this situation and, looking at his reply, I've decided: +Support IF THEY CHANGE THE FORMAT based off this reason.
I consider LTAP to be 2 things:
1. They are in a sit and LEAVE during the sit.
2. They are told by a staff member/are aware a staff member was there and will bring them into a sit and leaves the game.
If a player simply says they're gonna make a sit and the instigator leaves, arguably, I wouldn't consider it LTAP because a staff member wasn't present to confirm a sit was going to be made. Plus, as Bulborb said: "MAYBE because". This brings up the idea of CHANCE, rather than an actual confirmation.
