Facing allegations of plagiarism from a Pakistani cyberstalker

An article I have written, on Medium, in March 2020 about how western vloggers misrepresent Pakistan is challenged by the Pakistani cyberstalker Ramla Akhtar, aka Rama Aalam, on Twitter. She says my publication would be a plagiarism. Actually, the text of my article and its documents are original ones resulting from my researches and from my personal writings. As far as the subject of the article is concerned, it is not an “idea” invented by Ramla Aakhtar claiming her own « property » on February 2020. It is a hot topic from years before. My article is a detailed contribution but it never pretended having created the concept under review.
