@Semi_Hemi_Demigod They have a few things such as a return address to a government building on the envelope along with the envelope actually being a certain type that I haven’t seen with any other mail.
Sorry, I meant that if such a policy were implemented in the USA it would be abused by spammers. There would be a Supreme Court case where the spammers win because they used a slightly different color and it would suck.
We’re a young democracy and not very good at it.
It already is. Spammers use the tear-off style envelopes used for your checks or tax returns and many other ‘secure’ mail. The Republican party near me sent out mailers that looked like traffic bills saying how you may have to turn in your firearms (they were pretending it was from the local Democratic party). It’s already fucked here.
