Sedo Appears to be Hacking into My Account

I realized that all my feeds in artima have been, without my knowledge, replaced with a sedo site, a domain squatter, with my domain name as a query in their script.

Either they have hacked into my Artima account or they found some loophole in Artima site which they exploited to increase their page rank and effectively disabling all my feeds.

This is extremely nefarious activity and potentially criminal in nature.
