Catching ‘em all can be a daunting task, but Pokémon Go players who have turned to third-party modifiers to speed up the process could be permanently banned from the game.

Niantic Labs, the creators of the massively successful mobile game, have followed through with their terms and conditions on cheating by doling out permanent bans to violators. The company sent out formal letters Thursday, according to several users who shared them on social media.

According to the creator’s website and the terms and conditions portion of the game itself, cheating includes playing with multiple accounts, selling and/or trading accounts, or employing bots. Also banned is the use of modified or third-party software that allows trainers to alter their GPS signals, so they appear to be moving when they are stationary. This allows them to hatch eggs that require a certain distance, place themselves in remote locations to catch Pokémon, and take over gyms.

Additionally, some users are reporting that using stat tracking sites, such as Pokémon Advisor, resulted in receiving a ban.

Niantic does have an appeal process in place for players to ask for reconsideration in case they are falsely accused.
