But, as yet, no FB visit without UA...
Ditto. Always with a UA, typically --
-- or rarely, and as previously reported (see OP):
facebookexternalhit is NOT just visiting in response to a user trying to embed a link because it comes around far, far too similarly to the same page(s). Rather, it acts like a blog-host of a mother hen obsessively checking its chicks' links twice an hour.
For example, note the exact same '27 minutes after' hits to the exact same file:
Wait. There's more! Hourly hits to the exact same file at '57 minutes after' -- including one from "out-":
Those weren't the only FB-related hits that day, or even in that time frame, just the repetitively-timed ones. Coincidence? That 13 individuals tried to embed links to one of a half-million files every hour at 27-after and 57-after, to the second?
And to think I thought that page was wildly popular.
Anyway. Anyone else seeing similar same-time hits?
