// myUnreviewed provides functions to get message, profile, and attribute hashes the user has not yet reviewed

package myUnreviewed

// Each content to review has a priority
// Content that has been reviewed by the fewest moderators will have the highest priority
// Content that has been sufficiently reviewed by other moderators will have a lower priority
// Unreviewed content will be retained by the client until it expires from the network

//TODO: Add filter for ProfileLanguage, so user will only review content they understand
//TODO: Add higher priority for reported profiles?
//TODO: Add limit where if it has found enough options to review, break
//		-This means we will only need to search through a maximum number of contents before we settle on one that is the highest priority
//		-It may not be the highest priority out of all contents, but it will be the highest priority out of a subset of contents
//		-This would make the retrieval faster
//TODO: Extract errantProfiles from identity reviews and treat them like profile reports
//TODO: Add a toggle to consider/not consider profiles/messages reviewed if we have banned the author
//TODO: Build a cache to store the highest priority unreviewed content hashes
// 		-This way we only have to repeat the process after the highest priority unreviewed content has been reviewed
