I was chosen for a review copy of the OP's service, specifically the web 2.0 links. I got 10 links from 10 different web 2.0 websites.
The content were relatively long, though seemed to be spun content some of them were not too bad I like that random jargons were not just spun to get the content. They were niche relevant but still spun content. It's not that bad considering what one would need the links for. They are good enough for their purpose.
The link placement too was okay on most of them.
Overall, I would say I'm okay with what was delivered.
