Receiving Strange Comments

I don’t know who reads this, but if you do & know the answer to my question(s), please respond.

I am getting all sorts of weird comments & they are mainly coming from Facebook…I think. Also, the person commenting is usually addressing somebody other than me. Some have actually put a name of somebody (not me or even a previous commenter) in the beginning of their comment, & then say something that has nothing to do with my post. That’s the part that is really weird.

Any ideas what is going on? (I am putting all these on my SPAM list in the meantime.)
