Been using it myself for some years but the up speeds are really ass max I got was 5MB/s up. In speed tests ~300mbit up while my server was in an actual Datacenter with multi gibt connection I switched to proton and got throttled at 1gbit which is a lot better
Oh and someone was hosting a Tor endpoint on one of there vpns which gets the IP Blacklisted and you potentially banned from some trackers. support just closed my complaint without comment.
