No - and "illegal" is far too widely used
You really mean "Against policy". Like when you go to the gas station for a Coke and the clerk says you need to spent $10 to use your credit card. It's not ILLEGAL for him to require that, it's against Visa/MC policy. Yet, you will find people saying it's illegal.
The point is that at some point we will all be degraded for doing something deemed 'inappropriate' by someone else. Whether it was legal at that time or not is irrelevant, the damage will have been done.
Unfortunately the only way to protect yourself and your family is to leave a very small electronic trail. Why a small trail? Because no trail is considered 'deceptive' and 'probably hiding something'.
