Why has Facebook blocked my requests for 4 days?

[Happy Girl 20]

This happens when you send too many friend requests to people and then they respond to your friend request clicking that they don't know you personally outside of Facebook. Then Facebook blocks you from sending requests for four days. You will be able to send them after the four days have elapsed, but you should add only people you know personally, and only send requests slowly rather than adding a lot of people at once, otherwise you will be blocked again.

Hope this helps.Good Luck!
