Ask HN: Which Domains/Services would you block to regain some privacy?

Hello HN!

I'm getting more and more interested in privacy and already use different VPN's, disabled JavaScript in my browser switched to Linux.. well you get the point.. Now I'd like to block specific Domains like Facebook, Gravatar etc. that are known for disregarding privacy. Mainly stuff that tracks you while visiting websites.

I'd be grateful for any contributions!

Bonus Question: A while ago I found a big list of all Facebook related domains here but unfortunately I haven't saved it, anyone to the rescue?
