Todays finance regulators require you to not do business with some people, often without good evidence.
For example, if you do business with wikileaks, you will get a nudge from the regulator to 'reduce the number of high risk clients' you work with... They're not saying it's illegal, but they're also saying they're going to find some regulation to prosecute you with unless you do as they say.
It's a sad state of affairs when these kind of regulations aren't written in stone, but instead are flexible and applied on a case-by-case basis.
