Can you people read? He made SURPRISE appearances at the VMAs and the Brits, all for Rih. He hasn't gone to an awards show as an announced guest or got on stage to accept an award in ages, which is why I said FORMALLY ATTENDED.
Nothing wrong with their comprehension. Your OP just doesnt make sense. Ive never heard of a halfass boycott before. He's been at 2 award shows this year alone. Thats not a boycott period!
The last show he formally attended (edit: as a guest i.e red carpet/sitting in audience) was in 2013
