Was thinking of adding an avatar (random image I like off a search) and got to wondering this.
I think it’s fine if you’re not claiming it is yours. And most people assume that any generic/immediately recognizable avatar is just an image off the internet that the user just likes.
Though there’s maybe a weird grey area where if you use artwork from someone that isn’t like… a super established artist (hard line to draw) it’s kind of iffy. I wouldn’t feel right using someone’s drawing off Instagram. But plenty of people use anime avatars from manga etc. and I don’t see an issue.
Not the most important topic in the world but I thought it was fun to think about.


Technically illegal unless you are given permission. I don’t think It would not fall under fair use. (Depends on where you live)
Don’t think even a nintendo lawyer would care.
