I've signed up with them.
Impressions so far: well they're extremely brusque. The way they chat on here and the way they chat on Telegram. If it's AI they've managed to teach it to be as rude as possible. A refreshing change given the amount of flowery artificial nonsense out there.
It all seems to be paid by crypto, which I hadn't expected, but it makes the whole thing anonymous (if you pay with XMR) which is nice - not really a requirement for me right now but it could become one.
Not had a chance to really play with the server yet but the set up was brutally efficient and it definitely gives off Swiss vibes. So far so good!
