What are you guys talking about? The translators have always been rewarded for their previous translations and there was just week ago a translation campaign announcement on Discord to translate the GUI wallet again because lot of texts have changed since most of the languages were translated last time. Italian is already fully translated and will be released with new version.
We initially accepted only DaVinci and Utopian.io translators/proofreaders because the quality was higher there, but now we have extended it to community members too (people who actually use the app). Translations are funded from community fund (donations from Realname Attestation bot and fees from Username Attestation bot). There isn't that much to translate as there is funds in distribution fund, so your criticism on other distribution methods (draw airdrop is not the only one) doesn't make much sense.
What are the rules for these supposed rewards?
You need to signup on Crowdin, where all the translation are.
You translate all the strings, so the wallet is 100% translated.
You translate it so it actually makes sense and is not just a straight machine translation.
Somebody else needs to proofread all the strings.
Some chat bots can be translated too, but right now we translating wallet because it has had most changes, website probably will be translated again when the rebranding is finished.
