Are there any studies showing using 4chan, tumblr, or reddit has better mental health outcomes than non-anonymous social networks? I'm skeptical from my own experience.
Anonymity is an escape from the drudgery of this pseudo “real life” created by social media. You associate your real anything and you will pay the price.
Whether it be a photo or video, saying something that someone somewhere might find offensive—you end with all hurt and pain with nothing to gain.
The best way to engage with these platforms is to not take shit on them seriously and have fun (whether that's being a total flaming fuckface or otherwise). If some subset of the population can't handle that, that's their problem, and they should get off the platform; otherwise, everyone's well-being collapses down to some lame common denominator, and no one's happy.
A thing that sucks is that the platforms themselves are inherently at odds with their users' well-being. Not taking things seriously? That's low-engagement. Humor? That's bound to upset some advertiser, somewhere. No sex, no jokes, only solemn outrage with no bad words plz.
