The official bitcoin wiki, in this page (
https://en.bitcoin.it/wiki/VirWoX) says that you can buy linden dollars WITHOUT opening an account in second life.
Here's the passage:
"Technically, VirWoX only supports to buy BTC for Linden Dollars. However, you can first buy Linden Dollars for real-world currency, and then buy BTC for your Linden Dollars. It is not necessary to open a Second Life account to do this"
How do I do this?
That's true even at therocktrading, the other exchange that let you trade Second Life Lindens for Bitcoin.
You can deposit EURO or USD in different ways, convert them into Lindens and use them to trade Bitcoin.
It probably doesn't make any sense, since you can directly trade EURO or USD with Bitcoin (at therock),
but technically Lindens can stay inside rock or virwox accounts, without the need of a Second Life account.
(BTW, converting FIAT into Lindens into Bitcoin is the only method to avoid using Linden Lab Risk API).
