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

posts code in /prog/

Array.from (document.querySelectorAll ("div.post > div.body")).filter (e => "die" == e.innerText).map (e => parseInt (e.parentNode.getAttribute ("id").replace ("reply_", ""), 10)).reduce ((acc, item) => {
if (acc.length === 0) {
acc.push ([item, item])
} else {
last = acc [acc.length - 1]
if (item === last [1] + 1) {
last [1] = item
} else {
acc.push ([item, item])
}
}
return acc
}, []).map (ab => ab [0] === ab [1] ? ab [0] + "" : ab [0] + "-" + ab [1]).join (",")

So there's a limit of 100 replies for partial views.
