This is by no means a vital service, but Imgur. Not the image hosting part itself, although the multiple self-hosted alternatives available are mostly aimed at photographs and surprisingly very few if any to memes and reactions for chats, forums and social media. On the other hand, the particular use case of sharing memes and meme dumps is not being fulfilled by anything else at the moment. Go to Imgur even on it’s current sorry decayed state and at any time you’ll find multiple people sharing image galleries, usually of up to 50 memes at a time, sometimes more. Lemmy, Mastodon and Discord servers try to fill that gap but right now they can’t.
Just tried to create an account on fedia.io, which is the biggest of the mbin instances (at just about a bit above 4K users, so not THAT much), and it just could NOT take the registration, all i get is “429 Too Many Requests”, after multiple tries. I suspect that says the instance is woefully underpowered for the traffic it’s handling
