I hope for you that you use that advice as a rule of thumb rather than take it literally all the time. There are a few good games that don't have the comment section enabled. Tunic comes to mind.
Otherwise it's a good advice generally speaking. If nobody can review what the game is about, it's generally not a good sign that the game is worth playing/instaling.
They have recently went through and removed most of these files from the adult section. I only download ones with comments disabled just to see if it's in .EXE format and run it through virus total and then report them and give whatever info I know. Most of the files that get uploaded with comments disabled are because they're uploading older files. Take the corrupting the intern that has been recently posted. First the name is spelled with no spaces while the real version has spaces the file is in .EXE format the uploader is not the owner and the game came out in 2016 and was abandoned April 26 2019.
