They download a virus laden .exe to get you to run when you click on "download". That is coming from THIS SITE. It is a pure scam. Magnet links copied from other sites, no actual files, and lots of smoke and mirrors to get you to install malware and viruses. WORTHLESS
Be careful! It might have what you're looking for, but when you click on the download link, it often takes you to lo.ncdownloader.com or other sites that are full of viruses and have a really bad reputation.
The site itself is not that bad, except for the pop-ups and redirections when you click on the download links, that's what you need to look out for.
