Yeah... Got the same problem last year - one "clever" guy decided to steal my identity: he created social media profiles that duplicated mine (all personal and professional info, all links to my publications, all descriptions of skills and professional path), except the name and photo. The funniest thing, he called himself "Lester" (I am Lesley - got it? :) Now I use https://plagiarismcheck.org/ and other corresponding tools to check for duplications every file I create to prove my authorship in case of accusations. C'est la vie...
