Self-moderated threads in the gambling section are allowed. However, you shouldn't open such threads if the topic of discussion is someone's reputation or matters related to money. Also deleting legit posts that you don't agree with makes you look bad. Besides, everything that is posted on Bitcointalk will get picked up by Ninjastic.space and LoyceV's scrapper, so deleting it won't get rid of the post entirely. Moderating a thread to prevent the truth from coming out isn't going to get you anywhere.
Judging by your trust feedback, I assume this is going to be a self-modded thread about FortuneJack.
