I have read your past posts and your experiences of dealing with site scrapers.
Now that your site has gone real big -more than 30k subscribers- I am sure the frequency of your articles being stolen must have also increased (latest proof... http://www.labnol.org/forums/topic/a-word-by-word-duplicate-article-in-labnol) in that proportion, do you really go hunting after all of them?
I mean for one of my blogs, that has over 2k subs, I am starting to see problems..every 15 days I would see a clone would be ready...I am fed up of it now ... is it really worth to waste all that time and run after offenders, their hosts, advertisers etc.
Would like to see your comments on this issue.
