Interpret the meaning behind a comment that seems to be disguised as humor, but is actually meant to criticize the advertising of certain products and services in a comment section.
Of course the comment you refer to is more funny than anything else, but basically it is some sort of underhand advertising.  I think it is meant to illustrate that this comment section does not want to provide a forum for advertising especially not to witchdoctors and penis enlargers. I fully agree with that.
