Pages that I have never "liked" keep showing up on my Facebook Newsfeed. What gives?

[Nicole]

I have changed my password multiple times and haven't added any sketchy apps. I unlike every page that I see on my news feed, but I know for a fact that I didn't like these pages. They are random things, like bands I've never heard of, resorts, authors, etc. How can I stop this? How can I report it to Facebook?

I've seen it happen to a few people the past two days, myself included. All of them are promoting or selling something. It could be a glitch, but you can try reporting the pages, and see if Facebook does anything.
