I have lately come across several blogs and sites of HNers publishing their naked email addresses, without any kind of obfuscation. I admit that while I don't do this, I no longer check my (Gmail) spam folder for false positives. So, from <i>my</i> point of view it no longer matters whether I have tens, hundreds or millions of spam messages.<p>However, Gmail may care at some point! For those of you brave enough to do this, what is log10(|Spam|)? More importantly, do you feel it significantly impacts your storage quota?<p>Any further comments, as always, will be welcome. Cheers.
On a website I was working on recently I addressed this problem by slightly obfuscating the email address in the HTML:<p><a href="mailto:user(at)example(dot)com">Email us</a><p>I then wrote some JavaScript to modify the href attribute to be the real email address. So for the vast majority of people, they'd get a working mailto: link, but for the rest, they'd get a mailto: link which required them to replace (at) and (dot). Not perfect, but I suspect it stops the vast majority of bots.
~2.77 for me.<p>In my opinion, email obfuscation is like DRM: it doesn't hinder those who want to crack it for very long, and it just annoys legitimate users.
