To learn more, please visit our Help Center. If you think you see this message is in error, you can report the problem. "I do not know what the reason was blocked and for how long, people help me or guide me how to fix it, thank very much

Sometimes this error will come..wait for 2-3 days & then send friend request to friend. If you receive error message & after that you will send friend requests,then your account will be banned for 4 days or more than that.So wait for some time.

By a default error Facebook database has listed your profile as the one who sends frequent requests so considering you as a spammer. Nothing to be worried just make sure that you do not sent any more request and try to ask your friends to send your friend request. Have patience for a week at least, concentrate on getting likes for your posts or images so that you should be replaced in genuine Facebook user section as then you can send requests.
