I’ll just way in on this whole fandom thing again. Fandom isn’t a singular entity. It’s a network of dedicated fans trying to create huge databases and keep trolls from destroying their hard work. The bigger the wiki, the easier it is for something to slip by unnoticed. The Disney wiki admin team are great people, just overworked. I know these things from experience, I’m a staff member on a wiki myself.
As for a reliable leak source… you really shouldn’t ask about that on the public forum. Perblue doesn’t like that.
