Niantic's CEO, John Hank, said that they have dealt with players who use third-party tools. These third-party tools will display the location of sprites, such as the popular PokéVision. Immediately after the official discovery, the connection interface with PokéVision was switched off and the player who used it was stopped approximately two weeks ago.
In some cases, some tools collect user data and send it to Niantic. Hank says that this tool is similar to distributed denial of service - it will prevent legitimate users from accessing normal network services. Because these data are found to be malicious, developers can take immediate steps to protect the server. "Because we have to ban some players who like to use illegal software, this is of course only a small part."
Now developers are unblocking these players who use illegal software. "Those third-party map tools that modify data from our servers still violate our terms of service. If players continue to use them, they will still cause the account to be suspended," explains Hanke. He stated that as long as the accounts are created to modify server data or use GPS camouflage technology to play in other parts of the world, they will be permanently banned. "Our mission is to provide the player with a fair and interesting game environment." He concluded, "These measures will effectively curb those who are bad intentions."
