At one point, a streamer on Youtube asked his audience something like "Spam F's in chat [to signal that you like this thing I just did]"

Hundreds of users got banned by Youtube for spamming.

But they didn't get banned from "Youtube". They got banned from "Google". They lost access to their Gmail, and to their Android login, and every other Google service, meaning they lost their phone text verification system for every other login, and quite possibly their password manager.

Hundreds of identities were stolen and set on fire by an overly aggressive approach to spam management.

I try to remember this failure mode in planning (or being unable to plan) the security of my online presence.

Then I incorporate Elon Musk's recent behavior and recognize that while the profit motive _generally_ constrains the behavior of these firms, it's by no means assured.

For basic social welfare, either this identity stuff needs to be heavily regulated or all of these big companies need to be broken up.
