Can you please tell us what magical tools are you using that proves some coins are coming from hacks and stolen funds??
We use our own block sheets, and our own transaction verification systems. For some currencies, systems offered by specialized services are used, for example, for XRP we use a checker from xrplorer.com
So is this customer limitless_777 also being refunded to other address or not?
The user limitless_777 did not indicate whether his funds were frozen in our service and what order is in question, so we have nothing to answer this question.
