Our experience with their DUHL was very similar, and around the same time.  My post to NANOG about it is here:
http://mailman.nanog.org/pipermail/nanog/2011-June/037568.html

Despite the only public reply being utterly unhelpful, the post resulted in human contact from SORBs and an eventual 
resolution of the issue.  I have observed this pattern repeated several times on-list since then (and several times 
prior to my post), so it would seem that posting to NANOG is (or, at that time, was) part of their delisting process.
