I wasn't aware of that, and I agree that the way he responded may not have been the best way to do it, but I do think we should also take a bit of responsibility for not having tact. Aimsworth's post mentioned trolling and that implied that he wasn't being taken seriously.
From what I remember, his second post went something like "What would make it pixel art?"
His third post I think was where he misunderstood 1up to mean that we start at the pixel level instead of drawing the big picture first, and the pixel art style vs lifestyle thing he mentioned, I interpreted as, he misunderstood the intention of this forum as helping him to achieve a pixel 'look' rather than a pixel 'method.'
His fourth post he commented on 1up's rudeness, which I think was pretty fair given the way he was treated.
I think the reason why he was being so rude to you is because he thought you had read his comments before he deleted them and, as admin, you should have been more responsible, although you had not in fact read them and so perhaps that was another misunderstanding
I hope I'm not just being hung up over this incident, but he also PMed me and I kinda understand where he's coming from.
-- edit --- Maybe I should have PMed you about this too, Helm ._.;
