They try to get you to submit articles to them (usually for a fee too). But they’re kind of sham journals with no peer review or standards who no one actually reads. They’ll publish pretty much anything without even looking. They have bots that just mass email every corresponding author in every paper published just begging for submissions to their journal. Whenever an article is published in a reputable journal, one author has to have contact information publicly listed so they can answer any questions about the paper, and these predatory journals just scrape that info. It’s bad, so many emails every day.
D&d also explicitly describes female trolls too. Female trolls are also described as larger and stronger than males. Here’s a happy troll family from a d&d source book, lol.
Again not saying you can’t enjoy something or use it in an rpg just because the person who wrote it may have problematic opinions or it might have some mixed history. Like I really enjoy Lovecraft, but holy crap is it a mess in terms of racist undertones because of the author.
