What's fascinating here is that if you check the tweet of those scammers, there are a lot of replies that provide false proof of them receiving the coin. Dig deeper into those accounts and you'll be provided by evidence that they are just bots that are programmed to reply in those tweets so that it will look like a real giveaway. You can also check the specific address mentioned in the scam tweet and you'll be surprised that it received countless amount of coins, meaning people got actually scammed by it.
People should be very careful with these type of tactics. Bad people are always coming up with unique ideas to take advantage of those who are greedy.
I think those scammers are using "tweetstool" that you can automate's your comment, follow, likes and retweet.
And I think he can handle many twitter accounts to make his post look legit to fool other people that they are legit...
Just like what happens in blakchat niche if you are promoting a fake website and you wanted to make good leads you need to lie to many people just to make money.
The bad thing those people are improving their skills to scam anyone. So if you are not smart, you are not checking and reading carefully you can be a scam and lose your money forever.
Hope that twitter could improve their security and they don't allow twitter accounts with the same photo or image.
