Are you sure Mr. Yum said SORBS and not the useful scripts list?
http://bl.usefulscripts.com
I believe that means that youre not actually blacklisted, it just says that youre on a free host. So any link lists not allowing free hosts wouldnt list sites on that domain (pretty much all of them). Id imagine if you moved to paid hosting for that domain they would remove it.
