I would just like to add some cautionary anec-data: there are widespread cases in certain jurisdictions where rightsholders are known to seed the same torrents themselves, just to turn around and send love letters to leechers that connect to them. A good example is Germany with movies and TV shows.

Now, I don't know if, say, Wolters Kluver would/does the same thing, and what the realistic risk of an individual receiving such a letter is, but I think it makes it worthwhile to go over the actual law in your jurisdiction before diving head first on things like this.

I'm not saying it's wrong to seed these things, I'm just saying it might be a good idea to weigh the risks if you don't have a cool 500€ in cash to part ways with.

I had a letter one time when I was with Comcast, so I just spend the $5/mo and use seedboxes these days.
