The problem is that just about every post you have made and continue to make has had links back to your book sales site - or to the paper you wrote which has links back to the sales site. One can only conclude that the purpose of your posts are to sell your books.
I like to sell my ebooks too, but I do not refer to them in every post I make - not even the ones in my own private forum.
I would suggest a lot more posts with free information and no advertising or links. You can always put a link to your book in your profile and if people are impressed by your information they may wish to take a look and perhaps go to your book sales site that way.
