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

4 years ago, I made the mistake of posting on /prog/ to vent my disgust and horror upon finding out that the man who I’m engaged to has a fetish where it turns him on when women fart during sex. I was instantly swarmed by hundreds of JS programmers in the thread telling me that I’m a horrible person ... for not wanting to get married to a man who gets off to women’s farts! During sex! Yep, u heard that correctly. That’s /prog/ men in 2021 for u! Well, I broke up with him on Thursday night and he did not react well! He kept saying he can’t believe I’d do this to him, that his fetish isn’t even a big deal, everyone farts, blah blah blah. I told him I understand that he can’t control what he gets off to, just like I can’t control that I’m instantly repulsed and lose attraction to a man who gets off to women’s farts. He wouldn’t accept / understand that, and I eventually told him to get out. Being single (even if only for a week so far) is a breath of fresh air, literally! Thank u to everyone who msged me to support me. I still have loser men in my DMs telling me that I should be ashamed of myself. Uh, nope! It’s 2021 and women don’t have to put up with disgusting men anymore. The whole “no kinkshaming” movement has gone so far that I guess now I’m a bad person because I don’t want to pass gas during sex for a man’s sexual pleasure. What has this world come to?
