To accept something as true because a blog said so is to commit which kind of fallacy? ad hominem appeal to popular belief or practice appeal to inadequate authority slippery slope

The correct answer is appeal to inadequate authority.

Appeal to inadequate authority is a logical fallacy wherein we accept what someone says is true because they are allegedly an authority figure on a matter. In this instance, accepting something as true because a blog said so is a fallacy because there is no way to verify that the blog writer's claims can be backed up by solid evidence and facts.
