How nothing?There is this thing called "override transfer".Open ledger used it to transfer some shit coins in and out of my and other people accounts,i think it was "obits voting" asset.They (exchanges),people in charge on Bitshares network,have ability to override authority,they CAN!transfer assets from any account on Bitshares network,so..why the fuck don't they block this assholes,at least when someone gets scammed,they bring money back,or block gateways for scammers..there are tings that can be done,but no one is doing shit..this only makes good project (Bitshares) look bad in the eyes of new investors.
