Facebook group bug how to remove a member who's name is not on the list

This is very common bug in some of the Facebook group..especially large groups..admins get irritated when they want to remove a member and their name is not on the list as a result that member started abusing , flooding , spamming etc etc .their is a great trick send him/her friend request if he/she accepted search again their name on the list 100 % you'll get the name and can ban him permanently..Suppose if the user is not accepted your friend request make a girl fake id send him request if he will add make your fake id admin and ban him thats all!!!have fun :)
