Disclamer: This project got my venmo account permanently banned. No one was hurt during the making of this so no harm no foul.
This was a project that I made that would go to the public Venmo API page and get the last 20 transactions. Then the program would charge the recipient of each transaction a random amount between $0.10 and $0.99, and would attach a message that said: "You've been visited by Money Pigeon. Gift him and the Universe will gift you."
Before my account was eventually banned, I made a total of $5.03
Not too shabby.
