Let me be absolutely clear I'm not defending how he acted, I agree that what he has done is wrong, but I also think that this misguided notion that ericard has to be "grilled" to change his ways is equally wrong. It hasn't made any headway so far and it never will.
Well, now you're simply grasping at straws.
First, it HAS wielded results. First Ericard was happily publishing about his things without any obstacle (and even had people behind him cheering him up). Now he's known as twat by the biggest Castlevania forum. Not mentioning the FB group, where he was banned along with every mention of him or his work, which I'll bet were the best places he could ever speak about his Castlevania-related things.
I call this progress. If he's not willing to change, ALL these people are not willing to forget what he did. Every time his work rises, someone will appear to point at it, and point back at this discussion. The more people know about it, the less inclined/more restrained from showing it he'll be. That is, until the sprite is removed and he learns his mistake.
Second, by saying he "never will" is quite a weak assertion. We don't know that. I personally think he will, simply because he's being publically shamed into complying. If he doesn't, his game won't lift ground, simple as that.
