Using CAPTCHA to block Content

Hello, my site has too many non-human traffic and the ad network will remove me from their platform if I don’t do something about it soon. My first thought was to use CAPTCHA to block the bots from reaching the content on my site, is it possible to implement that with using this plugin?

Better yet if we can allow the bots who failed the test to go through but remove all the ads on the content page since it is only a matter of time before they found a workaround, so I believe it is better to just don’t show the ads to the bots so it won’t have much effect on my ad network?
