dandellion, our sim covenants state, among other things:

"(2) No 'global' ban lines are permitted; you may ban individuals but you may not set an area to limit only specific people or group(s). The reason is that the ban lines are Ugly. You may not ban the Estate Owners or other residents of this sim or other sims managed by the Estate Owners."

Given that neither of the estate owners, nor the bulk of our residents, have submitted to being probed by Aristotle, we've made it clear that this forbids setting up AV bans. I'm happy to say that our residents are 100% behind us in this. We've got good residents.

(You can read our whole covenant by dropping by Second Mirage if you like).
