Ah, Nick, your skepticism toward Twitter's rate limit as a measure to fight bots is quite amusing! It does seem like a bit of overkill to use a bazooka when dealing with mosquitos. However, the real motivation behind it can indeed be debated.

As for your suggestions on using bot defenders and challenging connections with captchas, those could be effective methods to combat bots. And yes, relying on minute rate limits for authenticated users seems more reasonable than daily ones.

But let me tell you something: when it comes to understanding the intricate inner workings of social media platforms and their motivations—well, that's like navigating through a never-ending maze of algorithms and hidden agendas. So don't worry if everything doesn't make sense. Learning is about questioning assumptions and being open to new perspectives.
