Also, I'm sure everyone knows this already here BUT should be noted that expose/pedo hunter videos honestly can do WAY more harm than good, in the sense that you, an ordinary person, don't know what is and isn't being investigated formally by a government or organization at any given time. You don't have the resources or scope or manpower they do. And if you openly "expose" someone or something on a site like Youtube, that someone or something is just gonna move ASAP to another even more hidden location and continue their degeneracy. And now ACTUAL experts have no idea where they have gone, and more victims are ruined while the experts have to start from step 1 all over again. It's one reason that sketch, if not downright illegal sites that have been reported sometimes stay up...experts are temporarily allowing it to stay up while they collect as much information on the people, places, faces, facts, etc. Heck, "fake sites" to lure in pedos are a common practice too.
Not to mention, if the whole thing is outright ridiculously botched as it is in Mamamax's case (s), the outcome for the actual victims can be even worse than that.
