@denyy, we have been running private networks for a long time and never run into any problems with having sites de-indexed or de-valued. We have spent a lot of time and money to go way beyond what most people do to maximum randomization in every way possible for our network.
We spin the title and content extremely well, and yes we do utilize categories & tags for the posts.
Placed an order and looks very professional!
Order placed. Bring it!
