Suggestion: Create a fast-paced two player game to revert bad immersion wiki edits in seconds.
The two players would see the original sentence along with two translations, one translation being the subsequent edit of the other.
Each player would try to pick the best translation.
If they both pick the same translation as the best one, they would get points and move on to the next translations. The translation not picked, if is final, would be reverted.
Translations/edits would come from across all documents based on the time they were written and possibly other criteria.
P.S. This is somewhat like the ESP Game.
