How is this ad hominem? This is like an article about cardiac health that says that we need to immediately stop administering Aspirin to the entire population written by an OBGYN with a plumber that sells Tylenol as a co-author.

It's an ad hominem because you're saying bad things about the author rather than bad things about the paper. There's a reason that blind reviews for journals exist.

I’m not saying bad things about the author rather that the authors don’t hold proper credentials so the reader should examine it carefully.
