> As an example, people lost their money to PayPal and had their accounts banned because their address contained a street named after a sanctioned location.
That is ridiculous. Modern companies have no problem Hoovering up and analyzing vast amounts of intelligence on consumers for marketing purposes. PayPal almost certainly has liasons with any number of three-letter agencies that also feed them intel related to criminal or terrorist activity. Link analysis and graph database software has reached commodity status; it's affordable and available. Directing them to do something to stop transactions between accounts known to be affiliated with terrorism is a reasonable request.
If their solution to money laundering bans accounts based on something so naive as terms found in a street address, their unbounded, colossal incompetence is not the fault of any government. PayPal has never had their shit together-- run-of-the-mill fraudsters have no problem keeping accounts open, but yours will eventually be seized without notice or explanation.
