New Super Luigi U Miiverse community suffers from ongoing hacks

For whatever reason, the New Super Luigi U Miiverse community has been the focus of some hacks lately. There's nothing malicious being thrown out there, but it's still facing hackers injecting their own content onto portions of the Miiverse. Nintendo is doing their best to combat the issue, but it seems to only egg hackers on more. Poor Luigi just can't catch a break.
