The mods will confirm that you aren't multi-accounting, so you will be cleared if innocent. The issue is more about why I, as a more experienced player, won't join games with 100 point buy-in.
The reason is that a new player, say, The Master, joins the game, plays all his points. The first 2 turns go by and he makes a mistake. There is absolutely NO consequence if he simply CDs the game. He immediately gets his 100 points back and can try again. Meantime, I've got 100 points - that I won't get back, by the way - invested in a game with people who aren't committed to playing. I have to wait 2 turns for the person to CD, then the position will often get picked up by someone else, and then half the time THAT person CDs. (There is some push to get Kestas to change this, to have a consequence to going CD).
At 30 points or so, I expect that maybe a new player won't see a bad situation as so hopeless - they have have 2 or 3 games going, and therefore don't need to get the points back right away. At 101 points, a player will have at least one game finished, so they're not a guaranteed CD.
