It's understandable, though I will also point out that the Image Guidelines are also listed on the page where you actually upload images too. This is a rare circumstance (as you pointed out) but it's part of the reason that guideline specifically is in place.
I didn't mean offense; rather, my point was that many have complained before about "rules" and "guidelines" not being listed on the site. I simply wanted to show that this one was truly in writing and not an "unwritten rule". Reading my reply two weeks later, I see that my tone may have come across harsh or annoyed, and that certainly wasn't my intent, so I apologize.
I'll never quit collecting entirely, but I am downsizing. Check out my COMC store and help me thin out what I don't want so I can buy cards that I do want. See something you like? Send me a message on here, and we can knock the price down quite a bit. I'll even take a bit of a loss if it means getting you a card you really want.
