If harry doesn't tweet, he truly is restricted as well, everyone around him went extra so we knew he was happy about it and appreciative and its' important to him because of everyone tweeting about it, he did last year so I think theres' definitely something with him as well.
Everyone around him tweeted including his managers, stylist, mother, sister, band mates. If he could, he would. This was a fan voted award, and I don’t think for a second that he would completely ignore that. I too think he was not allowed to tweet about this and I really really wonder why.
