Some WordPress Posts are automatically becoming comments on other Posts
This seems like a weird issue. I have published multiple posts on one of my websites. Sometimes, another post on my website (Post C) appears as comment under some other post (Post A).
The content of the comment on (Post A) will be some content of (Post C) surrounded by ellipsis. The author of the comment is mentioned as the title of Post C and it links back to Post C.
The IP addresses for the comments may or may not be different. Most of them are from Texas, USA.
The gravatar of the comment seems to link to an image trackback.png.
How can I stop these comments from appearing on the website?
