I am unable to add friends for a long time of period what happened?
Hey there SkullCandy,
A common reason for unable to add or accept friends is having too many friends already. This includes pending requests, meaning those that were sent but not accepted by the other player. You will want to log into the Battle.net Desktop Application and check your sent requests. You can cancel the requests from there which once done, should allow you to start accepting friends again. This page covers how to check if your friends list is full and cancel pending requests, including a screenshot for where to look and click.
