Spam is harmful and therefore bad, but I fail to see the problem with the "I am rich"-app. Is
it stupid? Yes. Is it of no practical value? Sure! Is it a scam or harmful? No. The person who
bought it by mistake has only one person to blame for the situation: himself. The description
of the app was accurate, the price was clearly visible, there was zero indication anywhere
that it was a "joke".
"I am rich" is basically electronic equivalent to expensive jewelry. Jewelry has no real
practical purpose either, and it's often used to show off your wealth.
