Likely not, the thing is that most of the big cloud providers definitely have a networking team and it definitely monitors for bittorrent traffic. The thing is they will monitor but until they get a DMCA you normally don’t get popped. However, some providers are more finnicky than others and will disable you immediately if you use 6881 w/o encryption. The key really is not to get a DMCA and not use default ports.
This is true for most providers but not the big big ones. Ask me how I know ;)
You would need to host your own or join a matrix server. The benefit of Matrix is you can tie in puppets to things like iMessage, Discord, FB Messenger if you host it yourself. Another option is Beeper (Matrix + all the puppets for other messaging apps) but you still have to sign up and get an invite from them to join for now.
Really don’t like Ombi, but music support would be nice
Private trackers work well if you’re already into that sort of thing
Good lxc container for those just starting out tho
