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

Hey, at least I got rid of the stallman spammer.

362 tightly grouped "die" posts >>8 without ban

Stallman spammer is the admin himself.
Genuinely surprised admin-sama didn't ban me for that
He is the site's admin.

Can you tally up the request in this thread https://dis.tinychan.net/read/lounge/1397591964 Commodore >>64-sama?

Added a simple stateful processing step >>71 to number the 362 >>8 "die" posts. https://dis.tinychan.net/read/prog/1582047203

posts code in /prog/
