I hadn't considered that, but it's a good point.
Oleg wrote:u_pm_download - for whatever reason we treat attachments in private messages differently from attachments in posts, to the point where I believe attachments in private messages are not even allowed by default.
Attachments in private messages are harder to regulate since only the sender and recipient can see them, so I suppose it makes sense to be able to turn it off for users in PMs but not necessarily in posts as well.
Oleg wrote:u_chgcensors - if one runs a board for pg-13 audience one may want to prohibit everyone from seeing censored words. Also, there are boards in competitive settings where they censor their competition, in such cases admins may not want to allow users to uncensor the board.
If you want to prohibit it, disable the setting, but there's no need for a permission as well.
