Mafia 84. Memorized it, turned it in, forgot it!

A very observant person could probably figure out the fourth one.

The fourth one is too unconventional. Posts are not formally part of a player's profile, especially since in this case, it wasn't even about a specific post, but about the hierarchy of a whole bunch of posts that are selected in your (not the player's) topics... It's crazy, to be honest.
