Profile people as... traffic lights?

I just don't think many of us believe that, "it's been happening in various forms for 20 years" is an acceptable reason to continue doing or accepting something.

You act as if Captchas themselves weren't created to prevent corporations from gaming the system. Like you do realize that the only reason that "every post you are making on this site blahblah" is because corporations just had to exploit the system for profit at the expense of literally everyone. Captchas don't exist because a handful of clever coders made bots that were able to skim some profits from Google. It's because corporations turned that into a billion dollar business. Capitalism ruins everything it wraps it's putrid tendrils around.

So yeah, no. "You've been doing it already for 20 years" doesn't cut it for me.
