yeah the big one that i'm aware of Blahaj--although last i heard they were also spending a ridiculous amount of hosting money with no obvious revenue streams to make up for that so i'm not sure if they've got that sorted out
Sounds like you made more research than i did. I just saw blahaj so i joined this instance. Was waiting for an instance to have close to a similar feel than my lgbt reddit feed had
Iirc, the admins said that they’re able to cover the cost of hosting (currently).
without a specific breakdown i'd always be a little wary of language like that in this space because it could mean "we have enough coming in to more than cover the cost and nobody should worry" but it might also mean "our admin/admins are paying mostly/entirely out of pocket and they're fine with doing that but it's not sustainable forever". (this unique sort of worry is why we're transparent with finances)
They've said they're paying out of pocket, though the only stat I've seen is that it's "significantly" more than $20 a month (which... could be basically anything lol.)
