From Ben Metcalfe:

The .ly domain space to be considered unsafe

I would like to warn current and future owners of .ly domains of a concerning incident regarding the deletion of one of our prime domains ‘vb.ly’ by NIC.ly (the domain registry and controlling body for the Libyan domain space ‘.ly’).

In short:

The domain was seized by the Libyan domain registry for reasons which seemed to be kept obscure until we escalated the issue. We eventually discovered that the domain has been seized because the content of our website, in their opinion, fell outside of Libyan Islamic/Sharia Law.
This is deeply concerning for everyone, but especially .ly domain owners, because it sets a precedent that all websites running on a .ly domain must comply with Libyan Islamic/Sharia Law in order to maintain their domains. This is especially concerning for anyone running a url shortener or hosting user-generated content on a .ly domain.
You may also not know that since June 2010 .ly domains less than 4 characters long may no longer be registered by anyone who isn’t in Libya – which suggests there is tension around foreign owned, high-value, short .ly domains.

Sucks for Bit.ly
