Which problem(s) are you trying to solve? Is it simply the time sink? If you think folks spend too much time here, then why not a daily limit? Make noprocrast a fixed limit for everyone. If you think quality would improve during "open" hours, then why not limit submissions to certain hours? Read-access all the time, but write-access only sometimes.
