I actually agree with Warbux that there should be rules or warnings before we go banning people. This community has consistently voted against punishing people for bad behavior, and mostly has only supported bans for hacking.
I think having a set of rules we follow is for the best, but I also believe in contextual decision-making and common sense. So, for example, the appropriate thing here (if people think Van is a problem) would be to announce a rule such as:
"Civil behavior is expected from players on this server. We will not hand down punishment lightly, but repeated complaints against a user can result in a temporary or permanent ban." Then admins can use their own discretion based on complaints and history if someone is running afoul of that rule. Tbh van is likely the only violator. But we should roll something like that out, with the approval of the community, and then wait and see how van behaves before taking any action against him -- imho.
