Spam is a plague for many WordPress sites. While it’s not nearly as bad as it used to be, every WordPress user can testify to how annoying comment spam can be.

Web spam can have far-reaching consequences: reducing engagement by driving users away from your comments and forums, hurting your reputation, and even damaging your SEO.
