What is wrong with stupid people

I was just listening to last.fm which is an online collection of tagged music that you can use to create an endless playlist similar to a radio station. There is one problem I can find in this amazing website. That problem is stupid people. God I can't stand stupid people. I created a station today that references the tag 90s music but thanks to stupid people that station is full of disco. That doesn't belong there. Last.fm is wonderful but anyone can tag the music. That includes stupid people. Thanks a lot stupid people for ruining my leisure time.
