Sticking by my original assessment. As a reader of RPS, I go looking for it in RPS comms - footie/PotC/TG etc. I don't expect general fandom comms to have it, so if I was looking for RH RPS I wouldn't go to robinhoodbbc anyway.

Also I reckon it's the responsibility of whoever's got the fic to set up a comm for it if they see the need for an outlet.
