sidenote, are memes allowed? it doesn't say anything about them not being allowed, but I don't see anybody posting any 🤷♀️
Two things. 1. Already mentioned, you need to be connectable. Torrent client port needs opened on router admin panel. 2. You can only seed if there is another user(s) actively downloading that data. And if you're 1 of many seeders, you're only uploading a little bit
Theres a lot more to it but thats a good high level overview
