I don't really think it matters how you label the kick, just that you kick the player that needs to be kicked. For example, if you have an extreme case where a new player that doesn't know their rotation and isn't properly geared is holding the party back from being able to complete the dungeon because they think their job should be played a certain way and don't understand game mechanics and continues to play in a way that hurts the party, that player doesn't necessarily intend to harass other players, but neither is he cheating or afk/offline. So something's going to be inaccurate no matter what excuse you use for the kick, but the player still needs to be kicked or the party is doomed.

I think it only really matters when you're reporting the player.
