@Fake Newts Yeah, this is the most 'intelligent' update for anarchies and their bgs so far. This opens gates for bounty and base raiding mats collecting tourists, but I am afraid that a proper solution would mean a really different standard for anarchies, which FDev won't imply any time soon.
Too tricky, I guess, since it touches too many different aspects.
An 'easy' solution, however, could be:
Logically (lol), a kill in an anarchy produces no notoriety, as it 'logically never happens' in front of any authority, which would issue a fine, bounty or notoriety. Both in space and on foot, one would still get their bounties through scanning, but cashing them in the same system
must not work on INF! Logically, when someone's death has no influence on society, 'cause that's the way it is in anarchies - one dies one way or the other, it therefore cannot change bgs INF...
Techhnically, like bounties cashed at an Interstellar Factor only produce REP. Only missions, trade and explo should produce INF in anarchies.
Like this, cmdrs would still be able to get bounties, raid anarchy bases without getting send to detention when they make a mistake, and it would not have any influence on the local bgs, respectively INF. Everyone is happy!
@Bruce G
For your initial question, here is the graph for Screaming Eagles in Kurughnaye from May to now. Pretty nice when the game forces you to "blaze your own trail" by playing a bgs janitor - apologies, a bgs facility manager - for several months...
And maybe you and the developers can give the INF idea I outlined above a second look...

Just trying to help...
