Strange Links

I am wondering why my Technoratti Authority numbers keeps on going down. I have been checking my links and it seems all solid. I am thinking that it's probably those strange backlinks I got last year from somewhere, are now starting to expire. I don't actually know where those backlinks came from. Those are newly created sites about loans that links my site from their post/site. I feel strange about it but thankful anyhow. When I tried to visit each sites, they are all newly created site and are not regularly updated. So their accounts are now probably expired or suspended that is why my technoratti authority numbers are going down. Freaky!!! Oh well, there so many strange things happenning on and off line, so I shouldn't be surprised about it.
