@xenia I know it's possible to make an instance using PixelFed (an image sharing platform like Instagram that shares the same protocol as Mastodon) and call it something like 'Pony.gram' or 'ponygram.social' (anything with a . somewhere between any 2 words)
@Shredd_Tone i heard about some pixelfed focused on pony fandom called pony gallery but the domain is down i see now qcq
@xenia If I had the time and patience, I would run one. Maybe throw in Sinstagram while I'm at it
