I am wondering why you are accepting strangers in your friend's list anyway. Also, their giving you their phone numbers is a sign they want something in return. please, Please, PLEASE delete these people from your friends list and never accept a 'friend' you have not met personally - this even includes friends of others. NEVER PUT YOURSELF IN SUCH A DANGEROUS POSITION! Never assume that someone you have never met is on the up-and-up. Please be more responsible.
