KBA is abrasive, and he has a rather strict ethical code.
There are reasons for both.
But he is a good GLer, a good person, and a good member both of GC and the larger online Pedo community.
And when he acts like this, it is because he wants to make sure everyone else is up to the standards he sets for himself.
If you're all right and you know you're all right, ignore the abrasive, be your best, and he'll see that you're reliable. If you choose to confront him head on, it will end with two too many people banned.
(It isn't gratuitos that infiltrated antis and Vichy don't confront him. ;) )
