> They also can't be stupid enough to not understand that using a single address that is blocked in most web wallets now is completely dumb.

Everyone always assumes stuff like this after every big criminal case. But every time it turns out that yes they were that stupid.

I sometimes get "we hacked your site, pay us bitcoin" spam via a contact page on my website. Once, I decided to send them a few cents to see if they were dumb enough to sweep it somewhere. To my surprise, they really were that dumb. It seems to be in some sort of wash trade loop (maybe a coin tumbler).

Shorting stocks will be suspicious if they do it from accounts who have never done much volume before. There are insider traders who are caught all the time doing 1 big trade (relative to their account values and previous activity) miraculously at the right time.

Definitely, this is like the theorized “Goldfinger” attack on cryptocurrencies—sabotage the network after building up a sizeable short position in derivatives. However a Goldfinger attack on Twitter stock would be a challenge to hide, since any evidence of anomalous trading patterns could open you up to prosecution by the SEC. Might want to check for any huge buys of daily put options on TWTR...

But why do it after hours then?

That's what I first thought of a potential better scam. Pump and dump. Emergency news covid vaccine gets emergency authorization or the opposite Moderna is pulled from next phase it killed people. I know the SEC is good at sniffing that out but seems like could easily get more than a few 100k especially given the Moderna news / earnings season

That's definitely one way you could blackmail people for more BTC, or unmasking various prominent anonymous accounts... Lots of way to use that info to make serious money on the darkweb.

Where does one go to sell or buy DMs like this? I'd like to take a look to see if or when twitter data becomes available.

Twitter is 24/7, it's a global company
