If you're part of the Western Touhou fandom, you should know there is a creeper going around inviting thirteen year olds to sex parties and trying to get minors' numbers and otherwise being like half a step removed from a child molester. The half a step is because he hasn't actually done anything he can be legit arrested for under the charges of child molesting.
His name is Erni Kim, and he goes by the handle Dakuj sometimes. Look at his picture. Memorize this shit if you're a congoer. Report this fucker to convention staff if you see him. Let's prevent the situation from turning into an actual full blown criminal "someone has already gotten hurt" situation.
Reiterating: this guy told a 13 year old girl to come to his room with condoms and birth control pills for a "special event." Enough said.
