Quoted from robin:When three moderators voted for a ban on a user, that specific user will be banned from the site for a week and 20% of karma points
This seems awfully overtolerant, there are some people out there (which likely are imbalanced in some way) that probably just shouldn't be let back, but I can understand this policy.
This site constantly gets updated and better as time goes on and is fantastic. I love to see it moving forward as it is. Thanks Robin!
