Yeah but most public trackers will give lots of side eye to torrents that contain an mkv that isn’t in one of those two formats.

Really? You think trackers download files and analyse their contents before listing them? I don't.

TPB? No. But 1337 and rutracker definitely do basic quality control. Nothing like a private tracker but they take down things like .mkv.lnk and similar.

You can report viruses on TPB's forum, there's usually entire accounts which upload viruses which are easy to find.
