Aliens with giant bosoms...now who wouldn't appreciate that?!
No close contact and observing us, or maybe they know people will gawk at their boobs?
I think the first thing we need to do is approach sightings with logic and find a reason for them that we understand, but when we cannot. Then one needs to start thinking, ok, this. Oils be something else. So many people shy away from what can't be explained rather then embrace it. I think there's something out there, purple tits or not, and it's feasible that they're among us jr at least flying around.
