Hi saurik, here's what I can tell from home on a Sunday night: - some pages on the domain were definitely hacked across multiple pages for weeks. - we detected hacked pages on the site both manually and algorithmically based on our hacked site classifier. - we sent a message via the webmaster console on May 5th to alert the site owner so they'd have a heads-up. - it looks like this has nothing at all to do with A/B testing (which as I've said before is perfectly fine to do). That's what I know with near 100% confidence. Here's what I believe, but won't be able to confirm until tomorrow when I can talk to a few folks. I think the domain was hacked in multiple ways. I found the hacked pages on model1.webdesigncompany.net just from doing site: searches. And you're right that those are auxiliary pages, not related to the main part of the site. But I suspect the core site was also hacked, based on looking at the manual action that was submitted. I'll be happy to talk to the relevant webspam people to ask for more details.
