Dealing with all kinds of weird download sites is the main selling point for me. It's not just warez, you run into them in all kinds of weird places where a nontechnical person needs to share files with a larger audience (google drive etc only works for small audiences), or where somebody decides to monetize by making a couple cents off your download.

With JDownloader you just throw the link in there, and the software deals with mandatory wait times, captchas, throttled downloads, "you exceeded your downloads for today, come back in 24 hours", etc. JDownloader makes sure it eventually succeeds without me having to baby-sit the process
