Well I wouldn't classify them as "Disgruntled". I would say more like surprised and imposed upon. A lot of people value their privacy and since they bought the device they feel entitled. While I wouldn't freak out I don't think that I would be very receptive to a stranger sending me PINS. I would just make some new friends here in the BB Messenger chat friend section and you will find a lot of new people that are willing to chat!
Good Luck!
