Crowdsource includes badges for each type of task and for other achievements, such as doing tasks in multiple languages, contributing more frequently, and doing tasks while offline. You earn badges as you contribute more to Crowdsource.
Note: In rare instances, a badge may appear for a task that’s no longer available in Crowdsource or no longer available for your selected languages. In these instances, the badge will be displayed as an achievement for users who have already earned it but will appear grayed out for all other users as long as the task is not available.
Note that badges for individual tasks also track your contributions to that particular task. The star on the badge expands as you reach each new goal for that task:
