It's becoming more clearer to me that there are people who have some kind of special access to servers handling the the interbank money transfers and who are trying to block or at least delay money transfers to Bitcoin exchanges (or at least they can dictate what kind of accounts appear in a "blocking list").
These are the reasons I believe this:
It happened to me first when I tried to do a money transfer to MtGox's bank account in France (this was in May or so while they still had their account). The money transfer did not go through and the software did not appear to register a transfer. I had to call up my bank and ask what happened. They were surprised themselves that the transfer had not gone through automatically but were able to release it manually. This actually happened twice and after the second time they send me email with the suggestion that I google the name of the recipient "Maracaja Sas" (the MtGox-exchange). The highest result of that Google was a complaint on these forums that their transfer to that bank account had not gone through. The suggestion implied was that it was risky to send this person money. I was thinking "WTF?", do the banks now check every person's reputation on the Internet whom I send money to?
I've *never* had this kind of experience with a bank in Germany and I have been using banks here for 25 years now.
Recently I've also noticed complaints by other people in Germany and Holland where banks other than mine are also making it difficult to transfer money to Intersango:https://bitcointalk.org/index.php?topic=53942.20
They make spurious claims that the computers of their customers are infected with rootkits.
Note that these are different banks than mine and they were trying to transfer to a different Bitcoin exchange. The only connecting thing is *transfers to Bitcoin exchanges*. This shows a certain pattern!
All the more reason to support Bitcoin!
