Consider this: i'd argue that the fundamental feature of twitter isn't tweets. It is the underlying certainty that the tweeted content belongs to the person with the blue checkmark.
My friends in social media positions heard about the twitter hack from me, not the other way around. Given how this info disseminated, combined with the breaking of twitters fundamental feature, i'm surprised more people didn't fall for the scam. A commenter yesterday claimed Coinbase had blacklisted the wallet very early on. I assume Gemini and Binance had similar reactions. Without this swift action, i'd wager the actual haul could have been many times the ~13 BTC they ended up with.
