A reference to The benefit of having a recommendation engine auto add stuff for you

A recommendation engine is perfectly fine and can be fun to discover new things you might otherwise not know about, but auto adding is a huge nono. You don’t want some random shit getting automatically added to your server and taking up space (or using potentially valuable/limited download credit from a private tracker) just because it thinks it knows what you want to watch/listen to/read. Automatically adding new stuff unsolicited it just a really bad idea.
