Lol, that's not how it was originally billed. Anyway, I think your argument here now is a trojan horse.
Your users are expecting a Dtwatter to get paid from. You'll have to deliver if you don't want to fail. It's better to just avoid that road.
It will bring zero value to the community and if it succeeds will destroy all the hardwork up to this point.
The service is meaningless if there's no incentive and will just overstress an already stressed system. There's not one tweet that's original that needs to be preserved on the Blockchain.
