Hey neveremail,
You were right on the vid caps and there's a blind link or two mixed on there, but mainly it's over-use of templates on those sites. You change backgrounds but the layout of the pages is pretty much identical and you're submitting to the same 2 or 3 cats with all of them so I just can't let it slide. I'd suggest you build a brand new site layout for your next 25 submits or so and then re-use them in order
