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

After my parting with Gaziza, she had a long chain of guys, and the bulk of this cut of the Russian nation turned out to be criminals: one stole her tablet PC, another used threats to force Gaziza to give away her gold earrings, the third was a heroin addict, the fourth, former Airborne Troops member, simply raped Gaziza, moreover he threw out of the window Gaziza's plush toys, the fifth - Richardov, the pedo+Linux-geek from Bostoninsk, turned out to be fixated on BDSM and coprophagy. Among other things, this Linux enthusiast wanted Gaziza to urinate into his mouth.
