So I was browsing around Instagram checking out the competition when I stumbled across a gun related page with ~220k followers. One of the posts contained a repost with a bunch of info on how to win this gun by sending $30 to a papal address, and how the raffle for the gun was limited to 100 people. I checked the account that the repost was from and the guy had only around 80k followers and had posted the picture within 24 hours, yet by the time it had reached the larger page only 9/100 places in the raffle where left. I then looked up how much the gun was worth, which appeared to be $2000 max, while this guy was receiving a total of $3000 ($30x100). Thats a $1000 profit he makes, and if you want to get extremely blackhat (and possibly illegal) he could have easily said the winner was someone that he made up and no one would be the wiser, while he runs off with $3000+. I hope this method helps someone, and sorry for my English.
