Yeah, it’s probably a legal thing, rreading-glasses is just metadata for books, completely legal, but readarr legality is less clear, so maybe they’re trying to prevent issues.
Also I didn’t understand what is rreading-glasses and why you need it
Say you want to grab a book by Isaac Asimov, you type the name of the book in readarr search bar, readarr contacts a metadata provider to show you cover images, author, date, etc. Then when you select the book readarr uses that metadata to search for downloads and ensure you’re getting the correct book and not another random book with the same name.
The problem is that readarr uses a closed source API for it’s metadata, and it’s constantly offline, which makes it impossible to use readarr. Luckily they allow you to customize the URL for the API, and rreading-glasses is an open source implementation of that API that you can use as a drop in replacement.
My point is that of those 120 probably 110 have never been compromised nor forced you to change the password due to expiration policies. The remaining 10 are the ones that require some mental gymnastics, so while the problem exists it’s not as serious as it sounds. I probably have more than 120 identities using this method since I’ve been using it for years, and I don’t think I ever had to use the counter, it’s a matter of being consistent in how you think about websites, for example if you know how you refer to a site slugify it and use that for the field, so you would use spotify, netflix, amazon-prime.
