I don't think the "connecting the world" was the problem. IRC also has tons of toxicity and connects people all over the world.
The core problem is gamification of social interaction. The 'Like' button and everything like it for things people say or show is hands down the worst thing to happen on the internet. Everywhere they can, people whore for karma (unless they spend a lot of mental effort to fight back that urge). How primitive the related moderation systems are directly affects how much primitive shit gets rewarded and alas, most moderation systems are ridiculously primitive.

So, dopamine hits for saying primitive shit.
