Trouble With Technorati

I have had some serious trouble with Technorati. I joined Technorati long after I opened this blog, about a year after, in August 2006, as a way of tracking links to my blog.

I noticed that sometimes, Technorati would not show some of the links to my blog. However, since the beginning of this summer, things derailed when suddenly Technorati cut in the total number of my links, more than 50, and later 200, links disappeared, while continuing to miss many of the important links to my blog. I wrote them four times and received the same unhelpful automatic answer over and over again. So I decided I don't need Technorati but I haven't been able to unsubscribe.

Do you have any alternative to suggest to me ? Or at least how to unsubscribe ?

Thanks.
