<prompt> Human: So it appears a debt collector has utilized Facebook to try to find friends who have their phone number listed and is calling my friends looking for me. It seems legal if my friends have their phone numbers publically listed, but is there any way to stop this. I have my friends list to only be seen by friends of friends, but now changed it to just me. But Im sure they have all data required.  <response>: adjust your privacy settings so only people who have added you can see your friends?
