New fun trick did you know if you Friend Request someone they cant add you to blacklist? Yup yup you have to decline the friend request... THEN you have to go in and decline the friend request AGAIN manually. Then you can finally click their name in chat and black list them as long as in that time they don't add you as friend again.... for PS4 users this is much more difficult task and takes several seconds and is incredibly annoying and bothersome if in middle of a fight etc.

Thats a tad off topic apologies
