You really don't need to be that paranoid bro for most people it's not that serious because if they cared about the information being leaked they would have never put it out there in the first place.Yes they can see what sites I visit but giving people the rest of the information about myself no.
That's what facebook wants them personal details that web browsing may not be able to tell them.
Our everyday thoughts no matter how mundane don't needs to be put on social media.
The shyt you're going on about has been known to the public since Snowden leaked it in 08 and even earlier...like, there's literally nothing new going on here.
The feds don't need facebook to track your info. They could subpeona your ISP and get your records, they could use your cell phone, they could use a combination of these things..what do you think you're doing by posting on the coli??
