I believe Twitter has made improvements compared to what they were few years back, so this may not be such a bad idea for Oscars. Twitter is now more keen to unusual and extensive activities detection made from the accounts, and is much thorough when it comes to verification and such. But as per the peace of mind and assurance for the bettors, I think it would be wiser to observe for a while and after some time they could place bets if and only if they are really decided.
