In fact I’d say that the harm to the trust in your parent that comes from such censorship pretty much outweighs the risk of reading stuff. It’s important to know what the kids do, but that’s to be achieved by having real contact with them and having them tell you that.

Which happens in many families I know, so before anyone says that’s impossible because of the „teenage rebellion”: too bad all the kids that can assert their independence while still talking to their parents about pretty much everything exist.
