What if you are toxic to an user, on the other side of your screen, who happens to have depression or other mental disorders, and you don’t know that fact? Would you feel OK knowing that you’re driving someone to hurt themselves, or worse?

This is probably one of the most important things to consider before posting something in a public space.

And this is not something that occurs recently or during the last 5 years. I’ve been browsing internet since 2006, and it was as bad as it is now, just with other intermediaries, like online chats, forums, etc.

What you describe here and above this sentence is true. It happened, it happens still. But, in my experience, not to the same extend. I 've been spending time in online communities since the early 90's and I believe there is a reason the toxicity is getting worse. Part of it is what @daredevil@kbin.social said. I mean most of the platforms offered by huge corporations try to drive engagement for profit. To achieve this, to get more people involved and engaging as much as possible, the interactions have to get limited to the least common denominator. It's not just reaction buttons, it's much more than this. Another part of it is the technological shift. The web was populated by significantly less netizens before certain technological advancements, with probably the most important of these being the smart phones. I believe this combination is the reason. The huge increase of people surfing the web and the appearance of huge corporations actively controlling how new people get used to surfing the web.

Btw at 2006 google was already there and quite big and facebook was already starting to get big.

Anyway, thanks for the link, as a fediverse newbie, I really appreciate it!
