I've been seeing similar scams in Elon's replies, they just copy his profile picture and name and reply with a different account. You might have seen that one
I couldn't find any screenshots, archive.org link, or browser history for the tweet I saw. So, unfortunately I have no evidence that the scam tweets started before Wednesday. We'll see what Twitter finds.
The tweets didn't come from his handle. They were using the same image and name but what really caught my attention was that those accounts had a blue verified badge.
Yep, the newest strategy of the Twitter crypto scammers is to hack verified accounts of lesser-known users, then change the account name and profile picture to that of the user they wish to imitate.
I personally saw one of the official @elonmusk scam tweets earlier this week.
