I was talking to a fellow user in PS Home, after a certain point I decided to go elsewhere and they became upset. They then decided to bombard me with friend request.
I was trying to respond by adding the person to my block list, but got an error every time I tried it. It said "An error has occurred. Try again latter." I decided to sign off for the night than continue be harassed because one of the core user protection features was not working.
If i am reading this right, it sound like it more of his fault you are having a problem blocking this than it being you. This might be a fault in his seystem. It might be somthing you will have to deal with i think and try your best to ignore. I had trouble like that once and it irritated the crap out of me. Turn my deystem on and i have like 50 friend requests from one dude lol. I know what its like but so far the only awnswer i have is that you will have to bear with it. Maybe someone else will have a better awnswer than I.
