So I was discussing Sugar with a friend of mine over Skype, somebody I haven't had an intimate conversation with in a while since she moved more than halfway across the country. I learned that years ago, when Sugar was first latching onto me, they also latched onto this friend of mine, sending her fucking shotacon in her Tumblr askbox. Like, out of nowhere. We were discussing Sugar and she was like "Oh fuck, I remember her, she sent me a whole bunch of asks and some of them were shota?" Also, she had remembered that Sugar had been calling themself Tony Stark for a while as well, which I had completely forgot about.
Again, this is years ago, and her word. She has no reason to lie about this, but I would have to do some deep digging to get evidence for this, and they've changed URLs and blogs a lot. I imagine most of those exchanges were private and long-since deleted.
I'm not going to ask my friend to join the forum if only because I don't know how comfortable she would be with doing so, but considering Sugar's association with Vade and having forced mpreg roleplay on a minor... not a surprising thing to hear that Sugar also liked the shota.
Then again, Homestuck obsession. All the characters are minors. There's that.
