Mystery Comments

​I’ve mentioned in previous blogs that I infrequently receive comments on my blog posts and those I do receive are from friends and colleagues.  Except one type of comment I receive.  The comments I receive do not appear in the comment section of my blog.  I receive comments directly to my personal gmail address.  I have a separate web e-mail account embedded in my website and I’ve never received a comment on that e-mail site.
I received an e-mail on March 21st with the subject of “reply.”  The post, as many of them are, come from an organization, not a person.  This post was from the college paper org on my post “Never Forget”.  I posted the blog “Never Forget” on 9/3/16 and didn’t receive the comment until 6 months later.  Below I’ve shown the exact blog comment:
                Study article to know what he wants us to remember maybe his advice will help
                Us to make our future bright in our career.  I would to tell everyone to know what
                is the purpose of telling us by that writer because his message is very special
                for us.
The first thing that jumps out at me is that the post was either written by an English as second language person – or a machine.  Second, the post is non-sense and doesn’t have full sentences.  Finally, the original post was about remembering 9/11 and my firefighter son’s re-enactment of the climb in Dallas, Texas.  The comment has nothing to do with the content of the post.
Where do such odd comments originate?  I don’t know.  I find them both a nuisance and insulting.  If I had a way to block them, I would.
Anyone in blog land have any idea on the source of such inane comments?
