You also forget :
-posting a singular "good looking planet" as proof that all the other planets having issues actually don't. Magically.

-claiming that it's "ReAlIStiC". Perhaps add some 70's blurry pic of the moon.
-take a screenshot at dusk, very low on the horizon and claim they don't see the problem. Obviously hidden by the dark, shadows and all that.
-will refuse to look at your stuff. Will refuse to even participate in the "study". Still claim you're wrong
-say you are misleading, lying.... Will not provide any proof that you are.
-will claim you took the picture in another version of the game. Even though planet gen was barely touched in the 5 patches, and you took the picture literally hours ago.
-will talk about the planet appearance when you talk about the quality of the texture, noise, and stuff like that. Saying "bland planet exist yo !", while you talk about PS2 texturing and "melted ice cream" issue.
-will cherry pick a good picture, and say you are cherry picking anyway.
I'd say you get used to it eventually, but you don't.
