if you seed like one thing, or each thing for like just a moment then it’s no big deal. whenever the torrent is finished, just delete it from your list of downloading torrents and you’ll be fine.
enjoy your free movie! unfortunately i have hundreds of gigabytes of free films/TV but no time to watch any of it haha
worst that could happen is your ISP gets pissed, especially if you only download things rather than seeding them (i.e. sharing them with everyone else). to avoid that only use a torrent client with a VPN, something you should probably just have anyways.
it’s really quite easy. use qbittorrent, it has a feature where it can search many popular torrent sites/trackers instead of having to search each site individually. unless you know any better never open a .exe file downloaded from a torrent.
i mean i appreciate all the seeders out there but i’ve been burned too many times to bother. it’s also incredibly inconvenient to keep files in the same place and with the same horrible naming conventions
