The copypasta originated from a tweet posted by user @ChiguQestirs (now deactivated). The user posted a screenshot of a direct message he received from an Animal Crossing player who appears to be a huge fan of Raymond. The direct message states:

Hello! I have been following your tweets for the past two days, and have come to the conclusion you do not deserve to have Raymond on your island. He is my comfort character and seeing him in an environment not meant for him brings me anxiety, so I will be expecting a reply to this DM when you have him in boxes and ready to relinquish him to someone who will treasure him like he deserves.
