I think you need to look at the definition of spam and realize that you are doing exactly that.
When a comment turns up in a thread which has nothing to do with the thread subject but seeks to promote its own agenda and is broadcast widely across a network, that is spam.
You can try to rationalize that you are helping people to justify your spam. However, commenting on every post with the same comment is spam.
HEY YOU IM NOT SPAMMING IM HELPING OTHERS AND ME .....DAMN UUUU
