This is not open to negotiation, please stop thinking it is. xD
Users can still modify their posts.
And the point is, once again, that if a user posts something bad about anyone else or the staff, and the staff DO NOT GET TO IT IN TIME, they could easily delete it BEFORE THE STAFF CAN SEE IT.
Again, this is staying this way for the reasons we've already given. You've still the modify button, be happy for that.
