The typo report could automatically include the surrounding paragraph/sentence for context and the editor could just correct the mistake and hit submit. Make it an extra backend module for the editors/translators or hire a dedicated person.
You could have all the suggestions go through a user critic before the editor sees them, I think the previous idea of a badge/exp/ss would get plenty of people willing to filter through the reports and peer-review them. Just dedicate a part of the site to suggested corrections. People can drift through and use thumbs up/thumbs down to filter the actual reports (have the report highlight the error for ease of use). Even better, replace the exp for reviewing a chapter with this; that would take care of two problems at the same time.
