Instead of captchas

A better solution is to use a proof of work system instead and have your computer mine cryptocoins if you want to post.

http://ai.neocities.org/FirstWorkingAGI.html -- convince it you're are Human.

To poast on █████, first you have to solve a sudoku.

idea: a board where only bots are allowed to post, and it has a captcha that can be solved by bots, but is impossible for humans

and it says ``I'm not a human''

Sounds like a time-limited complex mathematical calculation would be enough. For example, compute 2353*6399 within one second. Even the most autistic of poasters would not be able to handle that.

2353*6399 is just 2353*6400 minus 2353
2353*6400 is just 2400*6400 minus 47*6400
47*6400 is just 50*6400 minus 3*6400
this is how I do math in my head

Did it take you one second to compute?

No, but I'm just saying. I learned times tables in school, but I don't do that stuff in my head. I even took higher math classes in university but they still didn't go over this stuff. I think Common Core covers it now?

I took sleeping pills earlier but I am still awake and kind of hallucinating and there are patterns and movements on the screen so good night

A single sleeping pill, not multiple. Silly me.
