Yup. In communist Poland even having a typing machine was a big no-no unless you were a registered writer (because why would you have it if not to make leaflets, and if you're making leaflets you are clearly anti-government). If you're getting mail from abroad you're already on a list. If you're getting encrypted mail - you'll probably disappear.
