Okay I did a Blog post, there were comments and I commented in reply to one those comments, someone has now copied and pasted my comment as a post on their blog,

They didnt take credit for the post, at the top they had just added, this is real response, im not making it up.

Is that good form??? and should they be blasting it over all social media sites that they belong to.

Im a small blogger and get 50 hits a day, this person blogs must get several hundred to a thousand.
