That's the other part that confuses me... I can see someone being able to attach a name/address to a bitcoin address if they had access to the wire transfer data, but how would a random person on the internet be able to make that connection?
I was just going by the following:
We will probably never support firstbits addresses, think about it for a minute, by inputting someone's address I can instantly find out whether this person transacted with Instawire, what this person's IBAN and name are. Probably not the best idea when firstbits are often part of forum signatures.
I understood this to mean "If anyone inputs any bitcoin address into our system, they will be able to see the person's name and IBAN, so it's a good thing we don't allow firstbits, because some people's firstbits are available to the public and bitcoin addresses are not, and people might start seeing other people's personal information if we allow people to input firstbits".
