That's the whole point - don't treat "ccTLDs" as a single category, and the diference there shouldn't be between "exotic ccTLDs" and "common ccTLDs" but rather "your ccTLD" and "foreign ccTLDs". If you are in Afghanistan and run your business in Afghanistan in a legitimate way, intending to comply with Afghanistan laws, then there's no issue at all in using an .af TLD. And conversely, you should treat e.g. .uk and .fr as "exotic" if you're not in there and don't intend to spend the time and effort to learn about what is permitted there and not, it would make all sense for you to get kicked off of these domains by doing something that's obviously legal where you live.
