That is a good point you bring up. I've seen members post pictures with hats, outfits, doing goofy things, etc. With little to no backlash. It's one of those things where if you're a respected member of something(not with just chameleons, but in life), people give you a pass, even if you're doing something you probably shouldn't, while newcomers are going to get hit hard. You'll see that in nearly any social circle.
Just my observation on how people behave in general, not calling anyone out or anything. I was just thinking about this recently and your post reminded me of it.
