Usually NYT sets a cookie to track how many free articles you read and once you exceed that, you get the paywall. The bots probably don’t set/send the cookies, so NYT doesn’t block them. Also, I’d imagine the bots are coming from various different IPs so even server side blocking based on IP wouldn’t block everything and eventually the bot would get to the article. User Agents can also be spoofed.
This whole ruling is because of a person in power (Trump) who committed a crime (fake electors plot to overturn the 2020 election) and is claiming it as an official capacity of the office. That’s the whole point of the case which was appealed to the Supreme Court.
So what consequence will Trump face for his crimes now based on this ruling?
