Hi guys, So here's the deal: my competitors copied posts of mine from Q & A websites onto their site, keeping my links and content intact but adding the nofollow attribute to them. One of my friends recommended I use Google's Disavow Tool to get these links removed, what do you guys think? Should I be worried about this? The competitors have WP sites where they grabbed content from posts and they have low PRs, just like my site. I would greatly appreciate any help guys. Thanks!
