I think all sites should have a policy on the sittouts, this is unfair for the players. The sites that I have found to be really bad with sittouts are
Titan, CD Poker, spades lounge and most of the prima sites. This makes it really hard for players that never sittout, to have to deal with sometimes 8 players sitting out at a 10 players table. This has happened to me more then once, it sucks big time...
So I think something needs to be done, it's not hard to get right off these sittouts for them. Why won't the sites do something about this? They need only to get their programmers to set this up like other sites have done and it works so well. A lot more fun to play with a full table of players then have to deal with all those sittouts. It just makes the game boring and no fun for everyone and gives an advantage to players that are alone at a table bringing their chip stack way up.
Plus our finishing position depends on all those sittouts finishing after the people actually playing are out. I have seen myself being pushed out of a tourney, my finishing position if all those sittouts would have been booted out would have been much higher. How many times does a sittout end up at the finishing table, this is just unfair for all of us and to get to the money...
