While perusing a the ban list (for no apparent reason) I noticed staff have to manually ban people for invisible textures. My idea is probably stupid and not plausible. Here it is though. I don't know if its even possible either.

Anyway, I would like to suggest some kind of line of code in the shop that analyzes textures when uploading textures with an alpha channel (.png) must not contain less than X percentage of blank pixels or the system automatically blocks it. Something that tailors itself to the size of the texture as well.

Here's an example using no less than 70% of the area of the texture and 30% blank allowed.

16384 pixels in a 128 texture square means 11468.8 pixels must be filled with a color.
45875.2 pixels on a 256 texture must be filled.
183500.8 pixels on a 512 texture must be filled.

I just thought it would be useful for the staff because it's kind of a fire-and-forget solution to invisible textures.
