There's no way for a user to apply personal rules on his threads.

Yes, there is:

26. Local thread rules, if stated properly when the thread was started, specific enough and don't conflict with the forum rules, have to be followed.

In response to OP's question, theymos has previously said this about it:

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.)

So the answer is a bit vague, unforunately. It seems local rules shouldn't really be used for this purpose, but at the same time it's up to the discretion of moderators whether or not they enforce said rules. I have to say, it's very rare that I've seen a rule to exclude a certain user or group of users being enforced.
