Blocking Transfers at the Bank Level

[Jeff76]

I am a software developer who works for a bank. One of the programs I'm familiar with (but don't actually work on) is the international wire transfer program. The way it works is there are these published lists that we compare wire transfers to, and if a match is found then the transfer is blocked. There is a list for online casinos and gambling (in addition to terrorists, etc.) Our particular bank hasn't been enforcing this block before, but the head of international department just contacted us to add checks for gambling/casions into the system.

I understand the banks were lobbying against this because they don't want further regulation. However, it seems to me a fairly easy task from an implementation standpoint. Am I missing something? Is it just that the banks didn't want the liablity in case the lists were incorrect, or is there some larger issue in view?

And I guess the big question in my mind is whether Neteller and similar companies will get on this published list. I have no idea about that- just a software guy. But I am curious as to how these lists are populated and what organization maintains them.
