openoms on Nostr: Using only the order ID (a five digit number, no "rs") in the reference is obscure ...

Using only the order ID (a five digit number, no "rs") in the reference is obscure enough.
Should it become a general instruction to include it?
That would make the payer double check and provide verification to the seller that the buyer is part of the same transaction.

Also the order ID itself could be made to be random length letters and / or numbers so it is not a consistent pattern risking censorship.
