This torrent has DHT, PeX and LSD disabled due to the torrent being private and no trackers, but still is downloading, albeit really slowly.
How is it working?

Web Seeds?
Did it always have 0 trackers or did you just remove the tracker?
Could be an old tracker scrape telling a peer you have it and them attempting to connect to you.

If you connect to a tracker once, the client gets the peer list.
Back in the days people used to cheat by removing the tracker after getting the peer list.

This way you got the data, but did not report back the download amount.
