If they will not make it so you can unflag yourself, they should at least make it so that it is harder to set yourself flagged for PVP and definitely fix the fact that some other player can set you that way as you described. I just watched a level 60-something jump my wife's level 4 Jedi by using this same type thing to make her flagged. He then proceeded to kill her again as soon as she used the medical probe and was trying to figure out how she was flagged and how to get rid of it.
If you can't add the unflag button...do something about the abuses from jackwagons doing this sort of thing.
