If you cannot reply back to someone on Facebook, check to see if you have them blocked. You may also need to change your settings to include them in who can see your posts.
Facebook has determined that you were sending messages at a rate that is likely to be abusive. Note that these blocks can last anywhere from a few hours to a few days. Unfortunately, they cannot lift the block for you. When you are allowed to resume sending messages, keep in mind that it's possible to run into a block based on how many messages you send and how fast you send them. It's also possible to be blocked when either starting a new message thread or replying to a message. Lastly, deleting old messages will not allow you to send more messages. In the future, please proceed with caution to avoid hitting the limit again. Please be aware that further abuse of such features can result in your account being permanently disabled
If you completely deleted the messages, from the message box, you cannot retrieve your messages. If you cleared the messages from the chat box, you can go to your messages at the top of your fb page and click on MESSAGES, and your messages should still be there.
