LaDD vs. Honest

Player A: Control a face-up Light and Darkness Dragon
Player B: Control 1 face-up attack position light monster

Can player B use Honest from hand to bounce the Light Monster attack repeatedly by activating effecting effect from hand until LaDD warns out?, Or is the activation of honest require it to be sent to graveyard.

Asked on DN, some approved, some disapproved, some weren't sure.

So i need a final ruling about this.

discarding honest to gy is a cost, so it will be negated only once and honest will stay in gy
