Artist doesn't allows reposting of his images, it is even written at the splashpage... http://ukw.sakura.ne.jp/u_cup/

...which brings up an interesting point - do we respect such policies?

In case you haven't noticed, those kinds of rules are not exactly obeyed around here.

The rule is that if the artist finds out and comes complaining we remove their stuff, I believe?

First I hear, I don't recall that ever happening before.
