Twitter/X was easy for me, as soon as Musk touched it I closed that account. Wasn't too active on there anyway.
Still on Instagram but planning to close that soon. Facebook is a bit trickier with all the older friends/family on there that probably won't move elsewhere. Then again most of the friends/family I see regularly already stopped posting/commenting on Facebook so there's a lot of dead accounts on there.
Left Reddit during the API exodus.
Left my apartment window open once when going out, came back that night to find a pigeon just sort of wandering around. It clearly had no idea how to get back outside.
Took me a bit to corner it and catch it but I did manage to get it back out the window.
