Man they already answered, just forget about it. You should not give away your own translation jobs, that's not an excuse even if it were true, it is still your responsibility. Having said that made everything much worse for you, I'd give you red trust just for this fact alone.

You still cannot deliver a minimal clear translation, you need to read more and learn more terms. For instance, translating every single word to portuguese might be bad because we don't have specialized/established vocabulary for this area and sometimes it sounds weird or even more confusing than keeping the term in english.

Just assume your mistake, move on and improve as translator, it is not the end of the world.

Create and thread with sufficient evidence and I'll tag them all. Being a bystander to something like that makes you guilty as well (not 'you' as in erikalui alone, but rather anyone who sees that but remains silent).

Can't really verify work if you don't know the languages, which makes translation campaigns problematic. Checking various translation tools is not sufficient.

Forum wise? Yes. Campaign wise? Depends on the specific rules. This is classic capitalism / free market. For example if the bounty awards $100 for translation and you find someone else who wants to do it $50 for you (and you submit it for and get $100 - $50 (given to the person who actually translated it)), you're just good at doing business (given that the other person does a proper translation obviously).
