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

And Donald Trump did. “I’ve known Jeff for fifteen years. Terrific guy,” Trump told New York Magazine that year for a story headlined “Jeffrey Epstein: International Moneyman of Mystery.” “He’s a lot of fun to be with. It is even said that he likes beautiful women as much as I do, and many of them are on the younger side. No doubt about it — Jeffrey enjoys his social life.” 🐘
