It wasn’t bad at first

I’ve been on this site a few weeks. It wasn’t bad at first. But now, I’ve been finding the site is sending out flirts on my behalf without my knowledge. I don’t know what’s going on. Has my page been hacked? Makes no sense. I’ve never seen photos of these people, and they are getting messages I “liked” them, then they respond to me. I have to tell them, I never “liked” their photo. To make things worse, you can’t contact this company direct.
