I have learned so much from reading your blog I almost feel I owe you some level of support. Let us know what you come up with for a means of collection. Will it be tax deductible? On a side note can you share the identity of the worthless thief or thieves?
I believe even if you "register" each blog and someone steals it, unless you are willing to pursue it with a lawyer there is no reason for him to discontinue doing it. You can send a cease and desist letter but unless you back it up in court he'll just say , so what. At least that's the way i understand how it works with copyrighted photos. They both are intellectual properties. I could be wrong though, so...grain of salt....
Could you share with us who this person is or their URL? I would be happy to also put in a report to whomever is hosting this plagiarized content.
