Actual answer:
He is getting Concorded. He just doesn’t have any of his characters signed up to Zkill, so it doesn’t pull the loss-mails.
He manually posts the killmails, and its up to anyone whoring on the Concord killmails to post the odd kill on his gank ships.
Also your ‘friend’ is just trying to make the excuses for losing their ship, its unfortunately a very common response to accuse the other side of cheating when you are bested 
. Kusion gets it more than most because of his amazing multiboxing, despite posting vids of his ganks.
