If it's such an awful violation, then why not send a letter to Nintendo and/or Pokemon USA informing them of this nefarious activity going on right under their noses?
Because I'd like them to, you know, *not* put us into trouble. Wikipedia is not a suicide pact. :)
It's such a simple solution, I'm a little surprised that fair-use opponents haven't tried this already. (Of course, if the copyright holder officially shrugs about WP usage, or defines what they consider reasonable limits, that would make it harder to argue that fair use is always unacceptable, so there's a little risk.)
Fair use is fine. I'm an advocate of fair use. The problem is that *galleries* of proprietary images with no commentary are very unlikely to be considered fair use even if each image in itself is fair use in the right context.
