I had Cheetah pay a visit on one of my posts too, after I copied an article I wrote on Blogspot and posted it on Steemit. It's nothing to worry about, Readers will see that the link in the comment leads to my own work.

That's what copyrights are for. As the author, I have the right to copy and post my work anywhere I please. That is my right granted by the laws of copyright. A lot of people think that copyright was created only to prevent others from copying one's work. That is only one of the reasons. The other is to allow creators to make as many copies of their work as they see fit.

That's something any creator should take advantage of.
