Honestly Gravity loves P.Servers I think sometimes.
Especially with them taking sprites that have been made and putting them in their game. Too bad they won't take really good scripts from quests and add them to their game more if they would fit in well, but maybe they've done that before too without us knowing. :D
But yah if Gravity was wanting to shut P.Servers down it easily could. I think they will finally win indirectly when Renewal comes out. Its sort of Gravity's way of curbing them out without using the law, cause people will want to experience the new content and can't if they stay on privates.
Yah Gravity just trolled private servers like pros with this move.
