I checked out ScholarTown's short list of journal articles begging for reviewers. Apparently, would-be reviewers bid to review these manuscripts. The one I clicked on was for the International Journal of Psychological Studies (IJES), an offering of the Canadian Center of Science and Technology. CCSE has been accused of predatory publishing. IJES is offering $20 for a reviewer. The bids to do the work are coming in at $25.
CCSE referred to the same 40-year-old book review when it contacted me to contribute to one its journals. One of CCSE's addresses is, you guessed it, the same as ScholarTown's and Sciedu Press.

Kaye, Having read your article, "Book Review, The Right and the Power: The Prosecution of Watergate", we believe that you have considerable experience as an author or peer reviewer of scholarly articles. The purpose of this email is to invite you to participate in a new model for conducting scholarly peer reviews that enables you to earn from reviewing articles. ... Using ScholarTown’s online platform, publishers/editors can post article review projects that registered scholars can bid for. Employers (publishers/editors) can then select appropriate scholars for conducting article reviews, and pay them for work that is completed to their satisfaction.
