I can't help but make the obvious observation here. It's bitcoin... The space has a prior for people who are willing to rush head first into something they don't understand in order to attempt to make a quick buck. I'm surprised it was only 12 BTC.
But there's also a precedent of scams like this being posted on twitter, esp. from accounts impersonating e.g. Elon Musk. Just because it's tweeted by an official account doesn't suddenly make it less scammy - sure some people clearly fell for it, but I reckon most people using twitter with an interest in cryptocurrency would immediately recognise these tweets as a scam, regardless of the source
They used several different BTC addresses and even some Monero and other crypto ones. It's not just 12 BTC.
I hope Twitter's report includes a list of all the attacker's tweets.
