who and what is this

Let's if if the reply to this. I'm an open person and this Live Journal is for everyone, however when I'm getting strange Anonymous comments I maybe turn this into a friends only zone I do have my limits. A current example of this is in my post entiled NEXT MONTH to which they have replied "Many thanks for the article. I will have a link back to this information from our fresh blog. Thanks again".
I have asked them who they are and what gives them the right to link any of my posts to anything without my agreeing or givin permission but a lass nothing back. They don't reply all the time, just seem to be on posts when I say I'M ( as in me) going to do something and it's never anything encourging or constructive it's always really, or ok plus I don't know if it's the same person who is doing the "linking"

So we shall see what happen when I post this.
