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

I recommend you read your own Wikipedia article. I'm the dieposter >>130 and I don't even disagree with your opinions about Stallman or his political positions, just didn't appreciate a dead thread being bumped every single day with somebody's blog. Stopped coming here about two-three months ago and only check in to see if you're still upset. Looks like other people have picked up the spamming. At any rate, you're not being "suppressed" because of your opinions or positions, this place stopped being about serious discussion years ago, they're just fucking with you.
