Facebook limits

Hello,

There are limits in facebook. But i cant find them.

For example max post/comment/friend requests/friend confirm per day. Can you share this information.

Facebook Has no Explanation of any Limits
But after after adding 90 Friends in Old PVA you cant add more
You cant follow more than 500 or it will say your timeline will be cluttered so slow down
Every account and every set of friends that you add gives different also its not instagram
