It looks like some sort of site-farm and very very spammy:
eCoverNinja - Minisite Design | Condo and Office Rentals Singapore | condo-office-rentals.5ver.com
Hundreds of posts, each with a site framed within them.
I presume they are creating automated blogs and framing sites
within the posts.
I don't particularly want my site to be associated with it, anyone have
experience with these and is there anything I can do (at my end) to
prevent the practice?
