Not only are the scammers doing the fake accounts that say "send .02 BTC and get triple" but apparently now they are either buying verified accounts or hacking them and changing the names and pictures to cryptocurrency people. Now it can actually be hard to tell if someone is scamming.
Well if you have to warn a person to not fall for the "send .02 BTC and get triple" it's a lost case. Any human being falling for that is driven by greed.
