Copied Content?

Last night i was very surprised when one of the blog advertising emailed me that said, they will cancelled the review i made from one of their advertisers because the content is copied by another blog. If this continued, they will terminate my account. Thats very harsh, i never copied any content from another blog because i know that is one of their rules. Everytime i write review, i always write it with my own words eventhough my English is not that perfect but i tried my best to give a positive review. Hmmm i dont know how this happens but maybe we have the same thinking that time when we write the review. If you read my review and his review its really different but when you read it, it sounds similar. So anyway, i decided to changed my content last night so that i can still get paid with that review. But everytime i checked my account, they already canceled the payment of $20. Hope they can still pay me with that review, i swear i never copied any content from other blogs.
