I remember both the Artxilla boards and the Valhalla Comics boards each having an angry troll guy similar to that back when those boards will still around. The Artxilla guy was a fairly standard troll that mainly just insulted the artists that posted there and their art, but the guy on Valhalla Comics would not only disparage the art of anyone that posted there, but eventually began hijacking almost every thread with lengthy diatribes on American politics (even though he wasn't American). I'm pretty sure it contributed to the demise of the board. I certainly didn't bother to post there anymore, and some of the other regulars complained or disappeared as well.
I don't think it's coincidence that all these boards are gone now.
I got this one book that blows me away every time I scope it:
Oxide2 Carta Numinous - Kim Hyung Tae
I have that book too! I think he's an excellent artist.
I also have
Sweet Dreams and
Wild Flower by Shunya Yamashita which rank up there among my favorites as well.
