Ah yes... I remember this one now.
You were not showing as 'in lobby', so your character was alive and in-game. In other words, you had spawned, and should be somewhere on the main island of the game.
However, you were seen on Spawn Island (the initial location where player-characters are put, when they are in the lobby and haven't yet fully joined the game). Spawn Island is strictly off-limits to 'spawned' players. Some people think it is fun to go there (I shan't say how) and then kill people whose bodies are on the island, while the players are still in the lobby, waiting to spawn properly.
To be banned because of detection on spawn island, you either have to have been running around spawn island, shooting someone on spawn island, or otherwise causing grief, and (most importantly) not showing up as 'In Lobby'. Those are the signs that someone has gone to spawn island to cause mayhem.
I also notice that you (or someone else with the name 'Bane') appeared to have rather an unbelievably large amount of money - which was reduced to 100k.
Keep talking. Explain the above, please. It doesn't fit with your 'I was afk' story, so try something else, please.
