I just think you need to be cognizant of how Facebook is tracking you across websites as well. It's not just the information you have associated with your account, when you are logged into Facebook, you are tracked wherever you go. Now, there are certainly ways to limit this using plugins, etc.

Yikes- wow, even from my computer browser- not even from my cell phone? If I have facebook password autosaved, log in, check facebook, and close the window without logging out, is it still tracking me? Damn. I did NOT realize this.

I also recommend installing EFF's Privacy Badger extension. It shows you everything that is tracking you across the interwebs.

Look at any other website - is there a FB Like button saying "25 of your friends liked this"? Congratulations, FB now knows you visit that site.

Facebook reports of active users to their shareholders every month. You're an active user, you're valuable. The information you share via messenger, is equally valuable.

Use messenger.com instead of facebook.com/messages to get rid of the distracting notifications.

I do the same.only use it to message some people. I try to pull them into hangouts or signal because at least they are more or less jist a chat app so dont provide me useless notifications.
