There is plenty of ways graal can stop and or completely eliminate Ifiling all together,

Example change how things are saved, Don't leave it accessible for clients(Players) to view. You can make it possible where the game only saves certian files (Like default heads and bodies, things you can buy at Lavenders, basic heads like Nexus 8Bit heads. Things not a personal custom). And among a dozens of other things that can easily be done. One of the biggest issues i find with Ifiling is that fillers make customs less and less valuable, Less unique and overall I've seen many GFX artist simply refuse to make people customs in risk of ifiling. Literally like it you made top notch paintings for a living and someone takes them and say they made it
