Anyone can make an account, though, and instantly access that content, so Elon doesn't really have any leg to stand on by claiming they're private. It's not the same as Cambridge Analytica scraping stuff you had to have certain privileges to see by tricking the system into granting those privileges.
Elon unfortunately may have a leg to stand on, because it doesn't functionally matter whether "anyone can make an account and see it". I don't believe any legal ruling to date has been fine with that distinction.
It depends what you mean by "not allowed". Breaking ToS isn't a crime, but you might be sued for damages, but how can they show there were any damages?
But if they ban the nitter operator surely you can't just bypass that ban legally by making a new X account. That there are bans and the operator has to bypass bans by pretending to be a new person I think that this makes it different.
It's like a club that checks ids to ban people. I wouldn't call that club open to the general public.
Tall order. The main Nitter instances were using tens of thousands of accounts to evade detection, IIRC. Adding money to the mix creates more legal liability and a paper trail towards people who can be sued.
It's much easier if thousands of people set up their own Nitter instances.
Isn't Nitter abusing account sign-in for this?
