Bouchart: I don't want to be bothered by any of you chumps.
Go away.
Reverse psychology. In reality that was probably a plea: "Please love me! Add me as a friend!".
During one Steam sales, I tried to add as one of my old friends, which I knew at least used to have a Steam account, as a friend. This was because there was some achievement or something which could yield you some goodies (free games? cheap games?) if you shared or sent something to at least one Steam friend.
Anyway it didn't work out, he apparently hadn't used his account for ages so I couldn't receive any reply from him. No matter, I recall the prizes for meeting the objectives were something stupid worth nothing, some virtual badges or something. Meh.
That's my only experience with all these virtual friend lists, if I recall right. I'm not even in Facebook, for christ sake.
