You're right. In less regulated countries, they may be more lenient. But in countries with strong anti-fraud and anti-moneylaundering regulations, banks often will take the most risk-adverse course, which is to terminate accounts for very little reason and at the slightest hint of bad behavior.

I'm not against government regulation of these sorts of decisions, but to pretend that the regulations we currently have are consumer-focused in every aspect is just completely burying your head in the sand.
