not sure if this had been discussed before or how long it will last.
if you google site:-whateverhere (site:-123453, site:-fergregf, etc.) now, it returns 6 video results while saying "Results 1 - 6 of about 898,000,000 for site:-fergregf".
There're 6 pages listed at the bottom, but when you click on any page, or click on "Next", it just stays there with the same 6 video results on the page (URL does change to &start=50 but serp remains the same).
There are a number of ways to trigger "phantom" universal search results (primarily videos and books), but while there are suggestive patterns in the results returned, I've never figured out quite why it happens.
