A lag cheater is the most renowned form of cheating on PES. It is where your opponent is losing and they manipulate the connection so it disconnects (worsened signal) and the game becomes void.
If you’ve ran into a lag cheater, Konami asks you to send all reports of cheaters to email@example.com
Make sure to include the following:
Platform (Console it occurred on)
Date/TYPE of incident (i.e. lag cheat to worsen the signal resulting in a void game)
Your player name (PSN ID, etc)
Your opponent’s player name
