I mean the actions of predators also eventually resulted in the company and law enforcement actually doing something about the predators.

Being a part of the problem isn't a solution.

If you look into how these guys operate, it's not something you would support. For example they often conduct "undercover" stings where they pretend to be a child and exchange sexual message with other users in hopes of finding a predator.

In reality it's some guys sexting random Roblox users (who are, statistically, primarily children). It looks exactly like a predator's behavior, even if you believe their good intentions.

Law enforcement has procedures, some form of oversight of their operations and their interactions are documented.

These vigilante groups already existed, there's an entire genre of "pedophile hunter" content creators that lure people (including children who were pretending to be adults) into traps, often in person, and film them being harassed/assaulted.

Not surprisingly, they use tactics that are illegal for law enforcement, like entrapment and fabricating data, and have very flimsy standards of guilt (which become even more flimsy if they need more content).

These guys are not heroes, go watch their videos. They're people who want to illegally stalk, harass and assault people and use "protecting children" as cover.

You're buying into their cover without critically examining their tactics, methods and results.

It sounds real good right up until it is your 18 year old son or nephew is lured by grown men into a fake date, assaulted on camera and blasted all over YouTube or social media as a pedophile.

These people are scumbags.
