Thanks Mwookie...
I've suspected pretty much what you suggest. Although I wasn't thinking so much about the bots and spiders. That makes sense to me.
I'm actually quite intrigued by how the prime sites manage the whole procees of submissions to sort of slow things down a bit, whereas other sites are making it pretty simple to bring them all on.
In that vein, though a bit off topic, I'm not hearing from anyone in recent memory who made it onto ShutterStock without submitting at least three times. Which makes me wonder if they aren't actually slowing down the whole demo process with an edict to not accept anyone (regardless of their stuff) the first time through. Plus letting some photogs who won't try, try again" fade into the night.
Yes...I am a bit OCD. I do sit up late at night thinking about these kinds of things when reasonable people are sleeping.
Thanks for your insights. they are appreciated.
