1. I write graffiti. I don't pay too much attention to kids that only put up stickers.
2. If he actually writes like you claim, then wouldn't he at least be able to pull off a tag that didn't look like some random bum picked up a can and wrote on a wall for the first time in his life?
3. I'm not new to the sticker game... I'm not even in the sticker game. So no I don't know this sticker kids history other than seeing a youtube Japanese news report on him.
4. How can I be a sticker toy if I'm not even involved with stickers or the dweebs that only put up stickers? Congradulations, you're a dweeb.
