My point, is that literally ANYONE can submit ANY bullshit they want, and it can get published there. It's a clearing house. "PubMed has been reported to include some articles published in predatory journals. MEDLINE and PubMed policies for the selection of journals for database inclusion are slightly different. Weaknesses in the criteria and procedures for indexing journals in PubMed Central may allow publications from predatory journals to leak into PubMed." -https://www.ncbi.nlm.nih.gov/labs/pmc/articles/PMC6148641/ Here's a fun one! It's about "Perceived Stress Levels among Ukrainian Migrant and LGBT+ Minorities in Poland during the COVID-19 Pandemic" https://www.ncbi.nlm.nih.gov/labs/pmc/articles/PMC8657859/ Good stuff. High quality science-ing here. And these people submitted through a NON-PREDATORY journal.
