Hello, I would like to share with you the issues you have raised.

This GitHub project repository uses your stuff and is not open source

What do you mean that it's not open-source? The source is on the github link you sent and it's licensed under LGPL

It is in libs/gtolib.jar

He modified it and encrypted it without opening the file.

gtolib doesn't include any Ars source code as far as I can see. They do however have a mixin to the rewards system, which we'd probably want to flag.

After decompiling the jar, it seems the mixin just disables the reward functionality, I'd presume due to github.com being unreachable in China

package com.gtolib.mixin.arsnouveau; 
 
import com.hollingsworth.arsnouveau.setup.reward.Rewards; 
import org.spongepowered.asm.mixin.Mixin; 
import org.spongepowered.asm.mixin.Overwrite; 
 
@Mixin(value={Rewards.class}) 
public final class RewardsMixin { 
    @Overwrite(remap=false) 
    public static void init() { 
    } 
}
