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.
The crows I've seen seem to do this based on which dog it is. I've seen them stay put when it's a dog on a leash, but fly off when it's a dog that seems too playful/fast and isn't secured on a leash.
