Oh dangel....you are so out of your league. The tip for you to add a second ban was because you consistently fail to ban the person ABOVE YOU!
First rule....ban person above you. If you are too slow, or on a phone or iPad which hampers your ability to ban as quickly as you should and this causes you to misban it is imperative that you edit in a second ban to correct your mistake. First ban must stay.
So tired of explaining this to newbies....
Edited to add: Stina, please read and memorize the above!
