New link lists do this all the time to fill up categories. I wouldn't call it theft, unless they have stolen the descriptions from other link lists.
Enjoy the traffic and take it as a compliment that someone thinks your sites are worth listing.
You may find eventually that when the link list has enough real submitted links they will drop all sites without recips. including your sites they borrowed.
Remember that new link lists have a honeymoon period where they will get listed by much larger established link lists which will provide traffic boosts.
I firmly believe that
all traffic is good traffic.
