Google Translation:

We decided at short notice to deactivate "Everything on upload only". Files larger than 7 GB are still automatically set to Only Upload. Every now and then there are Multi-Torrents, just no longer automatically on all files, but somewhat more distributed and targeted. If you seed a lot and have problems keeping your ratio, we will help you, so you don't have to hold back when downloading, but please make sure that you seed your downloads for at least 48 hours so that you don't get to know our new H&R system.

There is also a Discussion-Thread for this.
