The screenshot from one of the replies to the tweet (https://twitter.com/pompompur_in/status/1437905607273635847) seems to be of qBittorrent. It's open source and cross-platform, just like Deluge.

Not available on my server unfortunately. Otherwise qBitorrent is the client of choice. I have found magnet links from DdosSecrets here: https://ddosecrets.com/wiki/Epik

Edit: Turns out I didn't give enough attention to Transmission as it handled the file. Very impressive.

As a side note: this has got me pondering about testing edge cases on open source software. Wonder how much of that actually gets done.
