I just got that message when I tired to add someone to my account: Block! You are engaging in behavior that may be considered annoying or abusive by other users. Facebook's systems determined your friend requests are being rejected at a high rate. Facebook aspires to be an environment where people can interact safely with friends and people they know. Facebook has limits to prevent unsolicited friend requests because this behavior has been reported as annoying or abusive by other users.You must stop sending friend requests to people you do not know. Further misuse of site features may result in your account being permanently disabled. For further information, please visit our FAQ page. It looks they will look on accept ratio ;/ Any ideas how to go around it ?
