Actually bc casino is using third party payment for tax evasion. Usually these merchants name them after famous companies having small alphabetical variation to avoid government surveillance
No, if I understand things correctly, then the fake name is actually for customer's behalf. I believe gambling is prohibited [either by law or by ethic] in your country? Many "gray area" business works with different-named-entities for their payment processor, so that the transaction won't reflect back to the payers [you, the customer] on your monthly statement.
For example, a bar that serve alcoholic drink named "Wine and Whiskey" will bill you under "Glass & co.", so that upon your monthly statement, anyone interested to see your monthly transaction will only think you bought 8,000 USD sets of ceramic antique instead of a bottle of Gran Reserva.
