The fact that someone was trying to push this Tuscon stuff on 4chan back in March 2017 leads me to believe its a black hat op. It seems like the plan was to make Tuscon go viral, then expose it as a hoax so that the well was poisoned before the genuine pedophile revelations came out.
I don't believe white hats would purposely stage something like this for any reason. They're more of "drop some hints and let people dig from there" types.
