Evidence? HA!
There have been two instances brought up. The missing kid which somebody helpfully showed the web page created by some hoaxter that attributed the identification to the police. You haven't shown that this was the product of reddit or any other sleuthing community or that it was the sleuths that caused the media to swarm to the parents house.
Then there was the blue bag guy who apparently named himself by posting on his Facebook page that he was going down to the court house to get it straightened out.
Only two people publicly and falsely
named and accused by persons who are idly playing armchair detective in their own living rooms? Well, that's all right then! Just the two!
Of course,
more people were publicly accused, but only by photo, and so, hey, no harm! At least, they didn't go public saying they'd been harmed by these public accusations, so obviously...
Note: it doesn't matter much whether reddit or any other "sleuthing community" was the source of the accusations. First, I don't know what a "sleuthing community" is, but so long as the source is online and neither a deliberate hoaxster nor professionally speculating, it's an internet sleuth in my book.
Second, even if the source
isn't an internet sleuth, the accusations were publicly repeated on widely read sites by persons I refer to as internet sleuths, and that's bad enough. Those individuals are responsible for that bad behavior.
It's apparent why you don't like Internet sleuths. You're not any good at it.
Your claim of all the harm caused by Internet sleuths will be ignored as so much hot air being exhaled by someone that doesn't have the facts. If you want to make the point, you'll need to demonstrate it with specific cases that withstand scrutiny.
Do you doubt any of the claims I made above and require citations? If so, which ones? I think that everything I've said here is common and irrefutable knowledge, but I could be mistaken.
