I'm still seeing it on tmbg, but thor and www seem fine:

http://thor.duckduckgo.com/?q=hiybbprqag

http://duckduckgo.com/?q=hiybbprqag

Edit: The same appears to be true for mbzrxpgjys and indoswiftjobinproduction

Edit 2: Hey, that's weird. Adding a comma, semicolon, period, or other symbol to the beginning or end of the query makes the gamed results show up on top at thor and www as well. Seems to work for all the terms at issue:

http://duckduckgo.com/?q=----hiybbprqag----

You're finding the edges of my intelligence layer :). Should be fixed now.

Note that some of those servers don't get updated often.

Ah. They were loading the same results as Google and Bing when I posted that. They aren't now.

There were a number of bugs around the first result that this whole thing uncovered, so it could have been intermittent. Our backfill in the case of no results can vary. It shouldn't have been showing anything ever beyond the first result though.

Thanks for the clarification. I use DDG as my primary search, and love reading about how it works.

It was there using those links when I posted, but not anymore.
