How Twitter CEO, Jack Dorsey, Restricted Advertising for Trump’s Campaign

It's interesting to see his perspective on it, but I can see how Twitter might want to disallow it for both candidates. It's one thing to help something trend like you would an ad, but you don't see the kind of negative advertisements for companies that you do for candidates.

Honestly I'm most surprised by HRC's campaign not asking to use emojis in their hashtags - that seems exactly like something her campaign would have done.
