The man sold a Sobble, which he had modified the details of with a PC, to a 36-year-old man in Kyoto for £30.
It is believed that the man has earned around £7950 performing this service for people since November 2020.

Players who are caught playing with hacked Pokémon will be banned from online play, and will not be able to access trading functions on Pokémon Home.
The company has also said that cheaters may even have all access to the Pokémon Home app revoked.
In a statement, the Pokémon Company said: “We will continue to regularly watch for and address improper or disruptive behavior in order to help our users enjoy a worry-free experience.”
