How does Nitter[0] work then? Does it use a Twitter account to grab tweets that reside in Twitter's walled garden. If the tweets are no longer public, how does such a thing work?
Public Nitter instances have a distressing tendency to become rate limited or go offline entirely. I'm on my 3rd or 4th instance now. That works most of the time though it's starting to throw limit notices periodically.
