Please make it permanent, he has absolutely nothing to offer, he never has, he is only here to troll, be unpleasant and purposely irritate, agitate and annoy, on any subject, regardless of good taste, subject matter or common decency.
He is a troll, nothing more, nothing less. Looks out for threads with anything that gives him an angle to come in on and write controversial, or just downright rude, comments. Sick? yes, unplesant? yes, annoying? yes, and I bet he loves all the attention too.
