Tomorrow's patch will disable "Ghost Training," which is the continuous skill gain on accounts in an inactive or expired state. Ghost Training will no longer function after Wednesday, Oct. 15.

For more information on the topic, check out this dev blog. It explains why CCP is doing away with Ghost Training.

There's no surprise that people have done this for the simple fact that it wasn't banned per se and also for the fact that it was possible. But recently we have seen a surge in this behavior in a way that we were essentially supporting and maintaining a large number of customers that weren't paying us regular subscriptions. That's not fair towards CCP as a service provider and it's not fair towards other players that pay a subscription but don't make use of this bug.
