Don’t need to put “exact” personal info on FB but you open yourself up to tracking by your IP address, and then of course there’s your conversations with “friends” that are monitored 24/7.
No doubt whether you put your personal info or not they know everything about you, your habits and your friends from the past.
The CIA plant aka Zuckerberg is an anti-American spy and piece of shit. No doubt similar to the Google crowd.
Both those companies are gov’t started, funded and owned by the CIA. Probably Amazon as well.
