After a bug with emty feed recommendations start to show many artists that already have been listened many times (like 40 times). I mean not the "All recommendations" section but exactly "artists" section.
The recent Radb outage caused the home page feed to be unavailable for many users. The short-term recovery strategy was to revert to a backup from several months ago, while the rest of the data was restored. As a result, if you're affected by this problem you may see outdated recommendations on your Home Page due to stale data. Sorry for any inconvenience caused by this, I've been told that the recovery operation will be finished by the end of the week.
