Phil Ringnalda writes about Dave upgrading the weblogs.com machine and finding someone crawling it.

I'm trying really hard not to think about how Dave was seeing a heavy load during the changeover because someone was crawling all over the Radio discussion group. Whether he meant radio.userland.com/discuss/ or radiocomments.userland.com/discuss/, in either case if I were crawling it, it would be because of all those juicy email addresses, sitting out at the end of /profiles/$ URLs all over the place. I've always thought those were fat enough targets to be well worth writing a special purpose crawler. (Note for the irony impaired: I'm not actually a spammer, or a writer of email harvesters.)

I hate to break it to you, but they've been crawled a bunch (and I know I've griped about it a few times here). They grabbed one of my addresses and I've gotten span from it. I personally think Userland needs to start encoding email addresses anywhere it prints them out on a web page (or find a way not to print them out at all, I personally don't trust the endcoding thing).
