It's Redacted.sh, a.k.a. RED. They have around three million torrents. But like What.CD, Redacted.sh is a private tracker, so you can't just jump in and see the content.

How does it compare to rutracker, especially for electrnic music? I've never used what.CD and rutracker seems to have lots of high quality music.

Thank you. I’m reading about them, cool project. I’ll try to join.
