We hate to ban regular members, and will try every means we can to avoid it. Spammers we ban without batting an eye.
Nubius is a great guy, but he went too far and continued to do so after attempts were made to get him to stop. I hated to see him go, and I still miss him.
While there are a lot of rules, each one was put in place because of someone's abuses. "95% of the rules are made to corral in 5% of the people."
The infractions system that came with the upgrade has made mods' jobs much simpler. Before it was a PM warning a member, and another, and another, until mods got ed up and banned them. Now, each infraction has a value, and they have a time limit. Once a certain threshold is reached the member gets a one week suspension. After that, if the next threshold is reached it is a one month suspension. There is an upper-most threshold that generates an automatic ban (currently 150 points).
