popular results are completely messed up. Today I searched several terms and on the first page are series from same shoots that looks much more like newest results.
Yup, most popular is still screwed up. They switched pages 1 and 2 a couple of weeks ago and it hasn't budged. The page 2 results of that particular moment in time continue to appear as page 1 most popular, at least for me. So if you were lucky enough to have a bunch of similars approved that day, you'll do well, I guess.
