re: "It could? Do you know something we don't know?"
There are plenty of stories in the Forum detailing such incidents.
Users have had their financial accounts locked and even had their money confiscated due to Upwork detecting irregularities with their accounts, or even with the financial accounts of clients they are dealing with.
Users have reported having their money taken by people who have hacked into their accounts and added new payment withdrawal methods. Sometimes users have indicated that other people (such as a family member or fellow agency member) had access to their computer. Sometimes they have professed complete unawareness of who could have done such a thing.
Users have left money in their Upwork accounts too long and been surprised when that money was returned to its funding source, because they weren't aware of the time limit that Upwork follows regarding how long they can hold funds.
Users have seen Upwork remove money from their accounts due to refunds and credit card chargebacks.
Users have been less than diligent about handling their own accounts and have seen Upwork trigger withdrawals automatically because the account balance exceeded a certain amount, only to see that number be sent to withdrawal accounts (PayPal, bank accounts, Skrill, Payonneer, etc.) that the user no longer has access to.
