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 ", etc. Not really "these people are banned: ...". (Though I have been thinking about adding a function to ban specific users from your selfmod threads.)
Ok, so if I got this correctly, local rule "user A is not allowed to post" shouldn't be enforced but it can be? 
Most people use local rules to prevent the truth being heard.
Any example? Or just another rant?If we are now saying local rules do not mean anything in meta that that is fine. However, it must be so for all members. I notice the very CLEAR local rules in my own thread are being flagrantly broken.
I am sorry to tell you but according to your local rules you are not allowed to comment in that thread:Local rules - only the most senior admin may comment on this thread.
Only Cobra, Cyrus and Theymos may reply. Satoshi can chime in, if he feels strongly about the situation, which I expect he would.
Now go and report yourself to most senior admin member. Only Cobra, Cyrus and Theymos may reply. Satoshi can chime in, if he feels strongly about the situation, which I expect he would.
