Alternative Social Networking to Facebook

I cannot tell which of these is a "honeypot" to mine your personal data or not, so use social networking with discretion. Maybe they are all compromised, maybe years from now they will each be sold or be acquired and all your personal data along with it. Whenever an alternative social networking website gets popular, the establishment big tech cartels try to shut it down, first by trying to buy them out (to shut them down), or by doing everything they can to stop ISPs from hosting them, or by doing everything they can censor and block these websites.
