So I'm not usually one to go off on disconnectors. They have their way of playing and, assuming they dc at the start of my invasion, I'm not inconvenienced much.
A few days ago, however, I bumped into a guy on his first playthough, who we'll just call by a similar name to his real one, "AlfBigGuy." Invading Anor Londo with my elemental Meat Clever build at level 36, I killed Alf and his phantoms numerous times as he tried to get through the level. Each time, I beat down his phantoms first and he disconnected once they were dead.
After every disconnect, Alf would send gloating messages about how he plays the way he wants and the stupidity of invaders... all in broken English and with no provocation from me. I never responded, because I knew he'd just return to the bonfire and I'd get to kill him again.
But then, the fourth time I invaded him, something different happened. Alf and his phantoms had made it past the archers and were passing through the fog gate to the interior of the castle. I made it to them and attacked Alf first, knowing that if he saw his phantoms die and disconnected he'd be able to keep his ill-gotten progress. Unfortunately, his phantoms were stronger this time, and a combination of a hornet BS and Wrath killed me, all while Alf sat back and chugged Estus.
More gloating followed, including from the phantoms who supported his cheating.
Then I did something I was never tempted to do before: I googled his username. Sure enough, an identical name popped up on Youtube with the same spoken languages and even some Dark Souls walkthrough vids in his favorites. Best of all, he had over 100 uploads, all of which contained copyrighted content from musicians and had a large number of views.
Needless to say, I flagged those vids. As of today, his account has been terminated for copyright infringement.
