The troller users are not forbidden here , the only (absolutly) thing that is not allowed : it is the spam. So you can report him to be " a spammer" but at the end the staff can do nothing because  technically he is not a spammer : https://bitcointalk.org/index.php?action=profile;u=375258;sa=showPosts.


I would like to be wrong, but it is up to the staff to ban him.


EDIT: I've checked in the log and his id does not appear #375258
