I have no idea if this has already been implemented, but I assume it is not
the case, therefore this posting.
Show factions will show the factions influencing you. I have no idea to what
extend this influence is, but it's almost certain it's a negative influence.
I'd like to suggest that factions (basically areas) tend to forget a certain
player after a while. E.g. If I (almost) haven't killed anything in a certain
area after quite a while, let's say a whole week, then there could be a chance
that faction forgot me.
I hope I'm getting the idea over here.

show factions should show your personal tune / rapeprot / whatever in that
certain area.

Here's example: I've been raping with my friends some area (like red_tides).
Show faction clearly indicates my personal tune in that certain area, general
tune can be something totally different.
