I get that, but it's not analogous to what I'm saying about internet communities. People with power and influence set the standards and hire people to enforce those standards. Cool. This doesn't typically result in mob violence though. This allows at least some modicum of justice to be applied by cool heads. I'm not trying to suggest that this is perfect or just, that's another discussion.
What I am saying is that on the internet, the equivalent of mob violence is common place. Gamergate being the obvious example, they supplied their users with guides on harassment and scripts to make things quicker. Take 10 minutes out of your day and harass this person. We found her parents phone number, take 5 minutes out of your day and call them and have some laughs. Multiply this by a thousand and you can make someones life hell because you know how to make teens mad.
I think there are a lot of shitty things beyond that because most tech companies are headed by people with a libertarian bent who believe in freedom and the marketplace for ideas and such. That ends up with Reddit being the largest Nazi forum on the internet, Twitter harassment being trivially easy, Youtube monetizing racists, and other such things. People that have shitty ideas at a young age (like I did) find it easier to find like minded people and possibly become less likely to grow out of those ideas.
I don't have a solution in mind or anything, I'm just whining that the internet sucks.
