It is useless, and cruel, to attack him, mock him and rage against him (a veiled form of bullying that has often been condemned here, in words, but then is practiced in general indifference).It can be unnerving at times, but know that he will continue to do so; either tolerate him, or ban him (if you think it's the right thing), but don't rage at him, don't mock him, please. I could not remain indifferent. Greetings.
