I'm not as confident here -- I'm not a believer in UFOs, but based on a bit of trawling through some of the more UFO-friendly areas of Reddit, it looks like the amount of photographic evidence has shot up dramatically, but no skeptic has the time or the inclination to actively discredit any of them, so they just fall into the echo chamber. The key point being that there are a lot of funny lights in the sky (none of which are UFOs) but all of which would require some actual investigation to conclusively prove they are not. That said, I don't see the same thing in Bigfoot land, so I think the omnipresence of camera phones has likely killed that idea. There are not as many funny unknown bipedal animals as there are funny lights in the sky.
