I'm using rapidseedbox.com, they don't ask for any personal info and I paid with crypto. The lowend plan I'm using is $9/month and doesn't offer many options aside from sftp access, 3 or 4 torrent apps you can switch between and a couple of other things. The higher end plans offer a shit load more like plex, etc. They will send a dmca notice and then like 12 hours later delete the offending content. I've learned that you can just restart the torrent and re-download it and all is well going forward.

There are a ton of other options out there for seedboxes.
