The American Institutes for Research has an ad on Craigslist for a test development assistant.
At the bottom of the ad, AIR writes, "Email applications will not be considered." But then the ad instructs the reader to visit its website, search on the job title, and apply through the website (read: via email).
Obviously, "Email applications will not be considered" means via the "Reply to" link at the top of the ad—the common practice for most CL posts.
Maybe the apparent dead end is a way to separate the potential wheat from the (clueless) chaff.
