as long as you don't do anything stupid (like post custom images to miiverse, there is an app for that) you are fine

Haha thanks. Yeah who would even think about doing stuff like that.

Its not that stupid. But as @Aletron9000 said, as long as nothing detectable was done on it, like a custom miiverse pic, then you're pretty solid

What's a custom miiverse pic?
