15 min timer for not banning. Harsh.
I would like to think that the timer for people accidentally missing a ban is very harsh. Especially, being that the season may be that people have running noses etc. But 5 mins, is good enough. 15 mins, and you piss off the 4 others you are grouped with. Please, add a chime, give it a vote for the other 4 people , what ever it is, but don't punish the group because one person had an interruption going on in their life. Though Major or minor, the general use of this tool to stop dodgers by the mere fact is too inclusive for the average person.
