I suspected some sort of internal tool was used to target prominent users but I’m still curious why there were thousands of unverified accounts tweeting the same scam. Searching for that bitcoin address pulled up tons of accounts tweeting it shortly before that term was blocked. Are there really that many trolls out there, or was a very large set of accounts hacked?
