All games, except tournament games, can be deleted before moving or even after a couple of moves! Note the timeout period, if it doesn't match up with the play you like, then delete it. People here may not WANT to move more often than once a week. Maybe they are busy, maybe they have occasional internet access, either way, if you accept a game with a long timeout period, then remember that YOU agreed to it. Tournament timeout/timebank periods are posted on the tournament joining page; if you don't like it, don't join a tournament.
By the same token, if people don't move within the allotted timeout and timebank period, then they have NO BUSINESS complaining. None. Is it nice? Maybe not. Is it fair. Absolutely.
Think of timeout and timebank periods like a contract with a bank. There is no leeway with it. If you don't like it, then go to another bank. If you are late with a payment, there is a penalty. You can complain, but you either pay the penalty or default on the contract (or forclose).
In regards to posted move frequency: that is NOT a contract. Maybe it was posted in error, or maybe it pertained to a time when that person did make moves more frequently. Sometimes I make several, even a dozen moves against a player in a day. Sometimes I wait three or four days, even eating into my timebank in an effort to look at the board and see the best move.
Remember, playing on this site is VOLUNTARY. You agreed to its terms, if you don't like the terms of a particular game, delete it, change your settings, whatever. If you find that this site doesn't have enough of the type of games you like, play another site or invest in/make your own.
