"Water Order" is slang used in the food delivery industry; it is not the official name of a system as announced by any platform. Some people use this term to refer to orders that have been pending for a long time, have incomplete information, or that they simply do't want to accept; therefore, rumors regarding the causes, penalties, or order-assignment rules should not be presented as official platform policy.
If you encounter an order that seems unusual, first check whether the pickup and delivery information is complete and whether there are any unsafe or capacity-exceeding requests. If you’ve accepted an order but there’s an issue with the merchant, customer, or address information, make a note of your estimated arrival time and the conversation details, then follow the app’s on-screen instructions for cancellation, assistance, or customer service; the buttons and procedures may vary by platform.
Rather than questioning whether an order is a "fake order," it makes more sense to prioritize safety, the completeness of the meal, and traceability.
