Edit about the 4chan image blocking, I asked Rimu directly:

I wrote a long message about how that checkbox only notifies about federated posts.

So the difference is for local posts it blocks the creation of the post entirely, but for federated posts it just notifies the admin.

A few people in the other thread assumed that it was required to fork the code to disable those filters. That's not the case, the filters can be configured, and are off by default.

To hide the reputation system, here's a line of CSS that admins can add in the admin area to hide it for every user

That CSS line can also be used by any user wanting to hide the score at the user level.
