Thank you HeptaCoin for bringing this to our attention, if you look closely at the authors/users who posted any of these articles you will see that it wasn't us as we will always do our best to use some sort of OfficialDuecoin name or variation of it; Steemit is a platform where journalists, bloggers, and basically anyone can write articles of interest and when a particular article is trending the author starts making micro commissions from it, this attracts people from all over the world to write articles of hot subjects and in many occasions they are not as proficient in English as they think or they simply don't care, while many of them will make a genuine effort to write properly, not all of them will. The best way to get, up to date, quality information is to follow us on our social media accounts. We are updating the information on the site but in the meantime you can search for Duecoin on Facebook and Twitter since those are the more active ones.
