It has been decided that a crowd will translate the content and translations must meet a minimum quality before being published. The crowd may or may not be receiving payment for the contributions.
The contribution of any single user can be of an unfit for purpose quality and for time or budgeting reasons open alternatives is not an option.
Let collaborators suggest a limited number of translations that are not visible to other collaborators before selecting one.

TxtEagle also uses limited redundant alternatives in their system.
