Polyphony Digital has confirmed it's commenced banning players from Gran Turismo 6, in light of new evidence confirming the use of illegally modified data in the game's online modes.
As stated in the official announcement, Polyphony has identified the use of "illicitly modified game data in the online services of Gran Turismo 6", and the users who've been caught have now had their PSN accounts banned from GT6's online modes.
The modification of game data for the purpose of "mischievous conduct against other players" is strictly forbidden by Gran Turismo 6's official terms of service.
Similar announcements to this have been made before – in April last year, the studio confirmed it had begun identifying and banning illegal modders in Gran Turismo 5 from that game's online services.

Hereafter, these Online IDs will no longer be able to access the online features of Gran Turismo 6.
Please be aware that usage of illicitly modified game data and any mischievous conduct against other players using such data are strictly prohibited, and will be subject to penalties as soon as they are found.
We ask everyone for their continued understanding and support.
