> a rule saying you shouldn't take drama from other sites to ours

The inverse is also a problem, and it's the one addressed by that type of rule. Taking drama from this site to other sites. If someone has pre-existing beef with someone else in your community, it's not ok if they bring that to your site, sure. But if Joe gets on Sally's nerves on-site, it's fine if she sends him a direct email filled with all sorts of flavorful harassment over it? And it's fine cause she stepped one inch over the border before doing it? Nah, they're both problems.
