Yeah, it’s about barrier to entry. Any question will bypass dumb automation, even hard captcha is defeated by a Task Rabbit or Fiverr job to make 10 accounts and post some s#!t
Probably at some point in the future, the automation tools they’re using will support throwing in a GPT API token. But AI calls aren’t free so maybe we’ll squeak by.
There’s also the real possibility that if somebody is actually using AI the bot text will be good enough that nobody will know for certain it’s a bot.
