Most of these messages are from automated bots, which is why the messages are so generic and lack specificity to the actual item for sale. It's unlikely posting something like that is going to stop a bot from messaging you.I've posted listings in the classifieds in recent months, and every one of them has gotten a response from a new account. I bounced messages with several of them who stated they definitely wanted the items I had listed, but no deals ever materialized. I have a new disclaimer I started putting into my classified ads:
Note: If you have a new account and have not interacted with the NES community (0 messages, 0 likes, 0 feedback), I am not interested in trying to work out a deal with you. These accounts have done nothing but waste my time in the past three months, so I will no longer respond to them.
