Well. I am sure you can do some googling (not as an asshole response). The service I use does torrent de-duplication, so if some other user has already downloaded that torrent, you receive it immediately instead of waiting, and you get $x size of cloud storage for the output.

They have an associated aggregator that has no ads on it, it's just a search bar and "What can we hook you up with?".

I pay $20 a month for it. Some may question what the point of paying for a torrenting service is, instead of paying the streaming sites. However, I used to pay for netflix and prime video, and I only went BACK to torrenting after things started happening to enshitify the product (like struggling to get full res videos because I run linux). The answer is simple: Ease of access.
