I'm a subscriber to Consumer Reports, so I received an email on what to do about Facebook apps in light of recent reports about misuse of users data. I also saw the information on Twitter, so I'm sharing it below.
I was surprised by all the third-party apps that were connected to my account. As recommended in step 1, I deleted most of the apps.
Step 2, turn off Facebook's app platform. It seemed like a good idea, so I did that.
Step 3, install a tracker blocker extension on your web browser. Sounds complicated. I'll try to figure that out later.
Step 4, on mobile, you can block location sharing completely. I guess that's for my mobile phone.
Step 5, delete ads you don't want to see anymore. I did that.
I've never answered any of those quizzes on Face, so that's good in terms of keeping my information from third-party apps. But, there were a lot of apps connected to my account. It was surprising.
