JoseBarroso's Journal: Spam Problem. Ideas?!

I have one resource, medical erectile dysfunction guide. Also I try earn on it. But there are in this world people probably to which my "business" is not pleasant, and of me try to make the competitor. Yes-yes, you have not misheard, - try. That is I say that I the owner of resource UsRxMed.com, not a secret that I sell medicines such as viagra, cialis and levitra. Also not the secret and that it I not one such, and now in this structure of earnings exists very great competition. Everyone tries to get in TOP of google, however not it is possible to all. Many, I will not be afraid to name their losers, having tried to make the way in this TOP "are refused" - at them leaves nothing also they wish to vent on the competitors a rage. This revenge can be shown as in the plan doss attacks sites of competitors at what all successively without analysis, also try spaming sites of competitors is that google has cleaned privileges from these sites, and has lowered them in SERP's on lower positions. And so, to what I all it? One more artful method has fallen to me. I have on a site a page - testimonial where my clients leave wishes, the experiences with reception drug's. At one time all was fine. And somehow suddenly in one day to me different spams-messages began to come. I did not know what to do with it, I was horrified and in a shock. I tried to change captcha's, but helped nothing, a spam came more and more. As a result I have decided not to complicate all it, and have simply made manual moderation therefore as any captcha was not effective. For what this post is asked by you? It for this purpose that people could reflect, as at times all happens simply. It is not necessary to search difficult decisions of a problem by means of various script's well enough to think and the decision will come to you!
