There is a company in the UK, Internet Watch Foundation[0], that works on this very problem. They were looking for volunteers sometime back to classify online abuse content and one of the requirement was "This is a tough job and only emotionally resilient people should apply....This is not a job for those on a personal mission, or for those who are easily upset by illegal online content." But now they are looking for paid part-time employees[1] for the same job. It is a tough job. There are other jobs available with them that are not that emotionally taxing.
