I left /c/Risa because the moderator there was letting his own personal feelings color rules, removing posts that violated no clearly written rules, and creating new rules without even running it past the community or asking how they feel about it.
The moderator of this community is guilty of that same behavior.
I'll be over on !whitepeopletwitter@sh.itjust.works.
I think it would need a full body disguise, and possibly to move, since I think they just wait to see whoever leaves a specific building.
I think crows can recognize faces and connect those specific people to cars and houses. I remember reading about a "study" scientists did where they harassed some crows while wearing face masks of former presidents or something until the crows got pissed, and the crows started attacking anybody with those specific masks on.
University of Washington is where that happened, or at least the time I read about it. They started wearing masks when they realized crows remember -and tell other crows about- faces.
