Not everyone worships same “Gedolim” you worship. I know they don’t let all negative comments go through, I have had some of my comments not published, and others I was surprised were published. Sensorship is a very dangerous thing, it makes intellectually dishonest people comfortable, but it repels those who have any integrity.
The inconsistency is sometimes due to different moderators, not different standards. Many posters like to hide their disrespect for Torah or it’s leaders behind inuendo or double meanings that are not always clear to everyone in the same way. As dangerous as you see ‘sensorship’ to be, disparaging Torah and it’s leadership is infinitely more dangerous.
