Not sure I understand the question.
If you mean about getting torrents that could be viruses the way it works I don’t think that would be an issue but they might have stuff in play to make it that way.
Given the torrents nor files are ever on your computer I can’t see it being problematic. Unless it’s possible to stream a video via torrent and that torrent somehow injecting bad code in.
Though another advantage to debrid is that majority of the content is cached due to the amount of people using it. So bad torrents would very likely not stay cached long but it could be an issue with more niche content maybe?
Lol is it bad this is the reason I setup a self hosted gitea instead of GitHub
