It may seem like “jumping to an extreme response” but once you’ve had enough experience in online forums you can see the storm clouds forming from a mile away, and you know you’re just better off with an immediate ban to nip it in the bud before it inevitably turns into a huge problem. People without experience see mods doing this and think they’re too heavy-handed, but it’s just basic internet etiquette to keep things friendly and clean.

I personally saw a few red flags, gave the admin the benefit of the doubt, but when the issue was raised enough to him, and he failed to ban the offenders, I knew exactly where it was heading and just packed up and left. The nicer places will move too eventually once they see enough of it.
