I'm confused. Wouldn't a human have to actually look at this site in order to figure out how to get a bot to sign up? Or are there bots clever enough to find sites on their own and try to figure out likely ways to sigh up & log in?

Do you have problems, concerns, or recommendations about the technical side of the Phoenix? Air them here. Compliments also welcome.
Beats me. We don't tell people about the confirmation e-mail until after they submit the registration.
I'm still trying to figure out what they hope to accomplish.

see anything interesting?

especially [link]
I'm seeing an interesting new attack on my website where the attacker is hoping to exploit unchecked fields in a "web to email" form. The attack works by assuming a field used in an email header (such as the "From:" address or the "Subject:") is passed unchecked to the mail subsystem. Appending a newline character and a few more carefully crafted header lines with a BCC list and a spam message body might trick the underlying mail system into relaying spam for the attacker.

Hmmph. I'm way too tired to see if they could be hitting our e-mail Admins page too.
Thanks for the lead, tommy.
Tomorrow.
Huh... that's kinda neat in an EVIL way.
Well, one easy fix would be to add a checkbox to both of those pages that says:
[] I am not a Buffybot.
If the box is not checked, then they're a bot. Poor man's CAPTCHA.
I've never used it, but this looks promising and fairly trivial to implement. Note that the author (rightly so) points out that CAPTCHAs are not friendly for the visually impaired, so that may be a consideration.
Edit: I just tried it out and it's very trivial to use. Pretty cool, too. However, IE doesn't render the image properly, 'cause IE isn't standards compliant. Too bad. There are other alternatives if you wish to explore this further.

Just got one from bergkoch8@aol.com which is funny because the next hit was to this story.
bergkoch8@aol.com is the other bcc address we saw.
I fucking hate CAPTCHA. I have 20-20 vision, and one time in four I find myself getting them wrong.
I'm going to tweak the script later today, to see what grounds we can toss these attempts on.
I fucking hate CAPTCHA.
Totally agree with this. The post tommy linked to has suggestions for blocking it.
You should probably look at the "E-mail Admins" form, too.
I *think* the E-mail admins form hasn't been used, because we'd get a copy of the e-mail to us. But I'll doublecheck.
Yeah, I didn't think it had, but reading that stuff on the other site, it seems like a potential target.
