Largest Maplestory hacking website being sued by Nexon America and Nexon Korea Corp.

Would this attract Anonymous toward Nexon?

I dont see why it would. Anonymous typically only targets groups that directly affect a mass public, IE: SOPA, Scientology, etc. this is a fairly isolated incident as far as the world goes, Its just 1 company trying to defend itself against some people trying to ruin their product.
