The stacked boxes did not show any box labels, sizes, or cw's thus it did not break any rules.
If a pic has multiples of the same shoe, color, same labels, and multiples sizes then it violates thread rules as it gets frowned upon as an attempt to resell.
Rules has been in place for many years. I enforce them, I don't make them.
You could, however, post pics of different shoes from different release as a collection pic. Multiples of today's recent pick-ups is not a collection pic.
Example: 1985, 2001, 2013, 2017
