This article discusses the challenges and problems caused by predatory journals in scholarly communication. By focusing on the editorial practices, I describe the case of Dr. Anna Fraud (Anna O. Szust in Polish): a bogus scientist created by four Polish scholars. Dr. Fraud became a member of editorial boards in over 40 scientific journals although she is a fake person and, obviously has no experience in journal editing. The present paper aims to show that scientist always have to care about a quality control and a peer review system. The article concludes with a presentation of the ‘Think. Check. Submit’ Initiative which provides useful and helpful tools for analysing journals by potential contributors.
