There is evidence of abuse in the sources provided in our comments, like sources of possible plagiarism.
When appealing, the user cannot provide evidence to show that is the author behind the articles in the sources, then it is obviously considered fraud and the account may be blacklisted. If blacklisted the user is asked to go through the next step of the appeal process of showing the ability to create original content. It is called an appeal because no user is forced to go through that process. They can always refuse and continue whatever activity they want on their blog. Blacklists are decentralised and so is our blacklist. Many users that got blacklisted by us simply ignore it.
