This one, in particular: the-exercise-site.com
I found the site commenting on one of my strength training entries, and then being listed as a referrer to my pages. Traveled on back to the site and saw the entry that the site left a comment on lifted, in it's entirety, and posted in their strength training "articles" section.
As a web professional, I'm more then a little miffed that this site is stealing content from other websites and posting it as either its own, or giving the impression that they have permission from the authors to do so.
Is there anything that the S365 admins can do about this?
