Local rules are enforced entirely at the discretion of the relevant moderators. It's intended to be for stuff like "you must post a picture", "you must make a price prediction", "do not go on tangents about services other than <this one I'm interested in>", etc. Not really "these people are banned: ...". (Though I have been thinking about adding a function to ban specific users from your selfmod threads.)

Local rules should typically not be enforced for these.

I think that I might make it so that new support cannot be added if the topic becomes locked or deleted, though currently this isn't the case.
