Teresa, at The Haunted Wordsmith, wrote out a post (which is no longer available as she took down her blog) a few days ago about a website that is harvesting the blog posts of many WordPress bloggers. That is, this site, tygpress.com, is likely posting on its site your posts without your authorization, approval, or permission.
You can check to see if this is happening to your posts by going to tygpress.com and typing your name or your blog’s name, or the title of one of your posts, or your blog’s URL in the search bar (see image above). Then scroll down to see if your posts are showing up on that site.
I did this and I found not only my own posts being published on that site, but the posts of many of you who follow my blog and who have responded to any of my prompts.
The hosting site for tygpress.com is Digital Ocean, and there is a site you can go to to report that your posts are being harvested by tygpress.com without your permission: https://www.digitalocean.com/company/contact/#abuse
I don’t know if it will do any good, but I did it and at least it made me feel better knowing I did something.
