(1) I liked joshi_tm's idea better, that every player can set an individual maximum amount of games (I think I could use it ;)). But that wouldn't fit your idea of avoiding to play too slow players. Therefor your point
(2) would be pointless. So let's assume from here on, that this feature would be applied. Point (2) are actually two points: The settings for tournaments are not necessary, because you could just set up a tournament without vacation days - so noone could "misuse" the autovacation feature. The second point about automatically putting "unrestricted movers" on the individual blocked users list would eventually cause a too high server load, because every time someone chooses (not) to be restricted, the blocklist of more than 20000 accounts had to be updated. And your Blocklist would be unreadable.
(3) I think that is too much for the servers also. People are demanding to only be shown the tournaments they may participate in since a long while, and it doesn't happen - But to realize it, you would only have to compare the tourney settings to your own data. If your wish would be applied, you would have to compare every tournament's player list with your complete Blocklist - everytime you look for tournaments. I think, that would really blow it up.
(4) That would be a gread feature! :)
