HasseKebab is right, it wont be long before random Q of items becomes outdated. These Q images are what you show your friends on Skype, not to random strangers on the forums. Factions probably also have quality metal that go way past that.
Of course anyone can post anything they want but no need to spam just cause you can. But general ruel of thumb is to have somewhat of an understanding to post something with quality so people 2-3 weeks down the line wont look back at the images and just see a bunch of outdated Q of metals. Would be a very boring W7 image thread.
