Yeah, this was my thought as well, and to me the "interview" reeks of dishonesty. Glad I didn't fill anything out yet.
Very likely. I wouldn't be surprised if Amazon still wants that information from workers, but I'd bet the messaging was taken down from the front page because someone said "That's really sloppy and careless implementation and it could come back to bite us". I still have an email in my inbox from MTurk requesting that information, so I'm not going to bury my head in the sand and pretend that the issue has 100% resolved itself, but hopefully we can all forget about this DAC7 thing for now. It just seems odd how much the messaging had changed in the span of a few days, and then how the date for the request was pushed from Feb. 28 to April 30 and then finally removed completely.
