  :I will make a brief summary of the problem: I started to rewrite the section “History” in the article on Brazil. The idea was to improve the text changing the old citations based on websites for books written by several renowned historians. I had already rewritten three subsections without having received complains from other users. In the fourth subsection that deals with the reign of Emperor Pedro II, I received serious complains from user  who made baseless personal accusations against me for no reason. I sent him a private message asking him to get into a peaceful resolution to the matter, but he simply ignored me and kept with the accusations, attacks and ironic remarks towards me. After that he added untrue information in the subsection. And even more serious:  he was not faithful to his own sources and created information that did not exist in the sources, as I managed to prove in the discussion page.
