You are the first person ever to complain about that. See I don't want to make new friends. I have my group of friends whom that I play with and have been friends with for years. I've tried adding new friends but a week or two later they don't play with you anymore and just take up space. I prefer to just do the achievement, say thank you and move on.
I can't believe that attitude. "I do not like random Friend Requests. You will be ignored or blocked."
-Then how would you ever make new friends? You make it out as if it's wrong to send FRs... I wouldn't be surprised if I was blocked for even mentioning it
