Did you know anyone can freeze your account on an exchange with one unblockable trick? - Divisions by zero

This week on “Unexpected Downsides To #Cryptocurrency”: Did you realize that you can’t reject #blockchain transactions and therefore anyone who wants to harass you can more or less freeze your “bank account” at an exchange like #Coinbase instantly just by either: a) sending a euro through a sanctioned mixer service like #TornadoCash before sending it to you or b) sending a few cents to a sanctioned terrorist wallet before sending you a single cent The automated systems used by Coinbase will immediately notice that you have interacted with suspicious or sanctioned wallets and Coinbase, which, like all crypto companies, spends as little as possible on customer support, will lock your account until you produce a passport for the person who sent you that tiny amount of money (often for months). These so called “dust attacks” constitute revolutionary new vectors in harassment.
