Given HN's incredibly easy signup process (not even a CAPTCHA), one would think that spammers would be going crazy in here. But I haven't seen a single bit of spam, either in the comments or new articles lineup.<p>How is this achieved? I mean what kind of spam filters?
I've seen a tiny bit of spam, and usually by the time I refresh the page, it's gone.<p>Sometimes in UK morning time, the spam lasts, oooh, 2 minutes instead of the usual ms. It's even faster these days than a few months ago.<p>And the community here is very zealous about the quality of submissions, and I bet a lot of people flag spam promptly.
