Right! I was very shocked with how straightforward the question was. Yeah for sure, they have plenty of data to monitor people. They actually can know a person very well just based on what the person "likes".

The biggest problem is how facebook treats its user....like property. Eliciting permission to do things that break privacy boundaries just by user agreement changes each year. Tech companies are all starting to follow there model of business and it is a complete invasion.

The usefulness if what keeps people using it but the privacy sacrifice is a great cost to pay.....more than even a monthly paid subscription.

Thanks, I found it on the search engine. I think it even has the screen name of the person who made it.
