The bill will not be accepted by anyone, so the only one who will see it is the person who printed it.

They could deposit it in a bank, but the bank will just send it to the Fed to be destroyed and replaced. (They have automated scanners that look for dirty, worn out, or defaced bills.)

So this is pointless if they want these notes to actually circulate - all they are doing is wasting money used to reprint the notes.

I used to see decorated bills fairly regularly, back when I mostly used cash. I was never aware of them not being accepted; it never bothered me.

One of my favorites, on a $1 bill: "Taxes are revolting; why aren't you?"

It's already leading to discussions all over the internet. It's obviously a successful stunt.

I've been given and have consequently used many defaced bills over recent years. You haven't seen all those bills stamped with things like that bill tracking website, or just random notes scribbled in with pen? If there are rules against accepting these, they're not followed by businesses I've dealt with.
