As I've stated before, I'm afraid we don't currently offer rewards for continued maintenance. I am also not even sure how we could design such a system that would not be abused. If we offered rewards for changing existing translations, for example, it would incentivize people to just make lots of pointless changes and claim rewards. We already have had to deal with worse kinds of abuse in the translation system.
Again repeating what I've said before, I simply cannot be involved in discussions about translation quality, especially as I don't speak a word of the language. However I will emphasize that good quality translations must be done in collaboration with the community. A good translator will listen to feedback and make any necessary changes. If a translator insists on their own translations against the wishes of the wider community, not only does that result in poor quality work, it could be considered abuse and result in a ban.
I understand how difficult it was for you. The fact that I do not want to listen to the community does not mean that I don’t have it. On the contrary, I have some people not on this site. They sometimes advise me how best to translate.
And these people who write here have not translated anything at all in the last 2 weeks.
But since the bonuses no longer work, I am still ready to translate because I love your project more than others due to its lightness. Thank you for creating this product.
