I agree, but you have to draw the line somewhere. Besides, you know there are some merchants who would abuse it. "I need a Mac beta-tester for this product." (With 15 zillion images.) The next day, "I need a PC beta tester!" (With another 15 zillion images.") The day after, "I need a Poser 6 user." (More images.)

Sadly, a few overly aggressive merchants have kind of ruined it for them all. They used to be allowed to post such requests, until a handful really pushed the limits.
