Ya Bit! Happened to me too.
I reported the links and got this nice shield here. I guess it’s the price to pay if your work is good enough it will be spread over the web for free.
i do have some script based automatic google query to check this things.
query is on my name, filters take care of removing known sites like envato mps, adobe cfusion, softpedia, etc.
i manually check the rest: most of the time, buyers also upload item sources instead of just swf/resources.
Can you share the script with us or me please ?
