I know right , majority of people expect a reward. You also have to raise an awareness to Indonesian community in general, to keep creating high quality content. I think you can write about a simple tips for translation especially if they want to use multi language so there won't be any bad translation. I think you're influential enough to write a post about this or maybe you can speak out my concern to other user from Indonesia, so Indonesian author could get more exposure worldwide with their neat and decent translated content :)

cheers, and good luck
