They won't pay me, but they still put ads on this blog.

     I have adult and mature content on this blog, so monetization is not possible.  Okay, I understand that.  So why do they still put ads on this blog?  I have no idea.  If advertisers don't want to be associated with my blog, they still seem to be there.
     I wonder what would happen if I cleaned up my blog, and made it suitable for a teen-ager to read it?  Would they review my blog, and allow this blog to be monetized again?  I don't know.
     I'm not interested in doing a squeaky clean blog.
     Also, I see nothing wrong with profanity, especially if it is funny.
