Yeah, this sort of shit is basically what I was worried Vivian would be used for when I saw her pop up on Danbooru.
It's fine if she's used as some sort of mascot of gamer nerds, but if she's drawn by Westerners and just going to be used for 4chan memes or spouting 4chan drama, does this really qualify as "anime related"?
We have MLP related images, along with things that aren't japanese but are vaguely animesque.
Vivian's creation is a bit more complicated but given that she is going to have her own game, maybe, and she is tied with 4chan's /v/ board whether it wants her or not.
see the drawfag tag and what sort of memes lie within.
