Say someone amongst your friends to send a friend request to you and by accepting his request your block will be removed. Otherwise wait for 7 days. It is due to too much requests lying unaccepted. Facebook keeps a friends and friend requests sent ratio, if the ratio does not maintained, your account put a block.

Taken from the Facebook help page: "If you've been prevented from adding friends on Facebook, it's likely because many friend requests you've sent recently have gone unanswered. This may be because you've sent friend requests to strangers, or it may be due to other behavior that Facebook members have reported as unwelcome."

Check the terms of service and make sure you're not breaking them. If not, it could be that your account was hacked. Change your password and security questions, then wait out the time.

Facebook tends to mark friend requests as spam if you send out too many per day. Only send out approx. 5 a day to be safe.

once you have sent a request it can't be unlocked. you have to wait until the person you have tried to friend rejects or accepts your request. if they accept you can go onto there profile and un-friend them.

Thank you for your question.

If you can't add a friend on Facebook, they may have not accepted your "friend request" yet. In some cases, the person may have accidentally hit the "block this person" link.

In other cases, they may have purposely blocked you.

The most common reason is that they are busy and haven't seen your "friend request" yet.

Sometimes, people respond to this a couple of months later.

You may want to track down they're actual email address and send them a quick, friendly note asking to "please friend me on Facebook. I sent you a friend request a long time ago."

If they don't respond, they're either too busy or they may have blocked you for some reason.

Don't give up.

Look at their friends and send them a messages asking if they know why the person won't friend you. (One time, I was the friend that wouldn't respond. I was in the hospital for 10 days!)

You never know why, sometimes. Some people just don't respond.
