"Sneaked references are references registered in the metadata of publications without being listed in reference section or in the full text of the actual publications where they ought to be found. We document here 80,205 references sneaked in metadata of the International Journal of Innovative Science and Research Technology (#IJISRT). These sneaked references are registered with Crossref and all cite -- thus benefit -- this same journal."
