You cannot avoid FB. They literally stalk you everywhere and sell your info to advertisers. You are their product whether you like it or not.
It’s easy to delete your account though. They may still track you, but you’re not feeding the attention machine.
You can protect yourself by blocking all 'social media buttons' (as LI or Pinterest do the same), and for FB block every domain they use and their range of IPs. But there are so many trackers that will (eventually) get the 'job' done, so you either do 'more' (replace hosts file, add firewall on your Android and block ad broker, doubleclick, adjust, mopub, google analytics, etc. etc (loooooong list).
