I agree with you on this. For the purpose of login in with a private key, i would prefer some browser extension (or built in the browser) that generates a key from a seed (like a crypto wallet) and only does that. This doesn't exist at this point.
> ... not to mention blatant fraud and manipulation aimed specifically and unsophisticated users
Also agree, but probably for different reasons. Many people on twitter have the tendency to be mean, twitter doesn't make people mean, but it amplifies it. There is so many scams and manipulation because scammers and con artists always existed and people's greed for that 100x token and so does the scamming
The speed of communication that the internet gave us also serves as an amplifier of the ugliness of human nature
