umm, just because 20 people are usin the same pass don't mean they are cheaters, unless you specify in your rules that you must use a unique password that no one else is using you can use the password hash as a means of finding cheaters.
Yeah but the problem was not only the pass..... like I said on my first message.. "3 account same IP same password.. and reffering each other... "
if they are not cheaters.. they REALLY have no luk to get refering each other choose the same passworld AND get the same ip!................... and nobody came to complain.... they are not ban from the site... just deleted..
