No captcha?

Hello,
I am learning programming and just discovered this website. But I am curious, how does it protect its users from spammers (people who post illegal or annoying things) without a reCaptcha? I thought clicking this blue box is required to prove that you are not a robot, can you please share any javascript that you use for this purpose?
Thank you and have a nice day,
Brian

I'm posting programming because this is the programming board. I'm also mocking /pol/cels >>190-201,204-215,218-243 as a bonus because it's a bit of a national sport in this part of the world, and /pol/cels are making it easy by being stuck for the last five years in this simplistic phase where the only technique available to them is stating the exact opposite of reality.

Stallman spammer is the admin himself. >>12
My guess is that admin got paid for PR Stallman as part of some political campaign. And since the money ran out, there was no reason force that thread further. >>14
He is the site's admin. He can run a script on the backend to post any kind of ads. >>20
