There's alot of translation Campaign, Be sure to be more competitive and no one will use google translate or else they will track you and not giving you a bounty rewards. for now you must join in signature campaign and get more rewards.
Doesn't really give any information on how to be more competitive, so here's my advice;
1. Get in early, this is the absolute most important point. Normally most bounty managers will select the first applicant for a language
2. Target a low competition language if possible, e.g. Mandarin or Japanese
3. Make sure your portfolio is easy to access, and doesn't take too long to go through, as they will just skip over it otherwise
