Facebook is a place for connecting with friends, family and other people you know personally. Facebook receives signals from the community and may establish limits to prevent behavior that other people on the site may find unwanted or annoying. These limits restrict the rate at which you can use certain features on the site, such as adding friends.
When your temporary block is lifted, please only send friend requests to people who you already know personally.
