How to brute force logins on massive sites such as facebook?

Hello there, im new to the cyber stuff and i know a thing or two about brute force and dictionary attacks. But when it comes to strict and huge sites like facebook and gmail, after some failed attempts they either ip ban or lock the targeted account(i suppose). So, is there any way to brute force/dictionary attack the login of these sites? Any kind of info will be extremely appreciated. Thank you.
