There's one more angle to this - apart from the raise in vigilante violence and messing up with police operations which both are very valid.
Just as we stopped getting TV feeds constantly equating pedophiles to child molesters, those guys stepped in to fill the void.
Pedophiles are not inherently child molesters. This kind of equation is not only wrong, it also adds to promoting dangerous behaviors among them.
Plenty of pedophiles will never abuse a single child, knowing full well it is dangerous and harmful for minors to be engaged in such relationships. However, the more we equate pedophiles to predators, the more people, especially in the emotionally vulnerable groups like teen pedophiles, will actually accept themselves in this role. Among those who stands against this anyway, plenty will become suicidal, not seeing an option to live a non-offending life.
Current methods of therapy aimed at reducing child abuse rates go very strongly on this - pedophiles should face message of them not being inherently dangerous, not the message of them being an immediate and imminent danger. Not only this is scientifically correct, it is actually useful in making these people safer for others.
