Spotted on Slashdot – but is this a rather obvious oversight (surely Google knows about having a robots.txt file?), or just a cunning way of trapping ill-educated spammers? My money’s on the latter – only a few hundred email addresses can be harvested from this, and if it was real, I’d expect that a few hundred thousand (at least) would have signed up by now.

And bonus points for anyone who tells me how to search the internet (using Google, natch) for the term ‘site:google.com inurl:gmail +”a-”‘, so I can see if anyone else is talking about it.
