If someone blocks you on Bowmasters, you can't follow him/her anymore or share a leaderboard with them. But if by mistake, you have blocked someone, there is no need to worry as you can always UNBLOCK SOMEONE ON BOWMASTERS. In order to unblock someone, go to privacy settings > blocking > click on someone's name who has been blocked before > unblock from there. If someone has added you as a friend on Bowmasters Mod Apk but unfortunately, he/she has blocked you, there is no way to send a friend request, but you can still chat with them by sending messages.
