have got an account on it but rarely use it,plus have never used it to talk to random people,only ex support staff.
dont worry about those guys that have a friends list as long as the great wall of china-made up of random people they just add to look popular...
because of their desperation for popularity and their trigger happy friend adding,they always end up hacked under FBs 'name three friends on their list' rule,hackers make up three accounts,get the target user to accept each of their fake accounts,then they name their fake accounts as friends and do whatever with their account.
am constantly being asked by family to add them,but have always made excuses such as 'its an old account that is now inactive',adding others woud be far to much communication and woud end up becoming more mute as a result.
with a new account,have been thinking about accepting sisters invitation just as a trial to see how it goes and also to nosey at the photos of some of the people on her list as have known them just as long as she has.
