While reading some regulatory documents I was wondering, it would be great if we can have a blacklist feature available of addresses that makes deposit transactions through related networks to halt such transactions to be appear on the exchange or possibly stop withdraws of such accounts who performed transactions.
Tt can even be done in a plugin. The plugin subscribes to deposit/withdrawal through redis pubsub and listen to the events. Once such event occurs (blacklisted address), it would freeze the account.
Freezing account can be done by setting user’s activated flag to false.
