Slave Keys - When you give the proper key to a slave, nothing visibly happens. No dialog, no faction, just eats the key.

Taskmaster Earring - * - The NPC asks for a bronze earring but the taskmaster only drops a brass one ever. When you hand in the brass earring, nothing visibly happens, no dialog, no faction, just eats the key.

These quests are important because they help evil players gain faction with the [wood/high] elves and dwarves.
