First thing, whatever name you choose, don't use "Twatter"
The problem with every so-called decentralized no censorship no moderation project is that you're going to have to compete with spammers, I've just checked the link icopress posted and look at the last activity:
https://peepeth.com/new , it's a total spamfest.
Also interesting from their FAQ:
Peepeth is spam-resistant because it costs money to write to the blockchain. Don’t worry— Peepeth foots the bill for you— but spammers lose their free-peeping privilege, making spamming a relatively expensive prospect.
So they do censor and ban accounts....and yet...
The other problem is money, poeple will not want to pay money to post their views on the internet, and when you're going to incentive them to post bots will take over, bitcointalk was no exception, no project will be one.
Why do you think the tokens (if structured the right way) couldn't drive incentive? Each token is worth one message. This would have to be well thought out but it would eventually become a "pay-to-tweet" service which is fair because there has to be a small cost for the service. Just as there is a small cost to use any blockchain technology.
And what would give enough value to those tokens to make them an incentive to either mine or post or host a node website?
If we talk about this kind of token one can't stop thinking about Chia, it started as a total hype, scared every HDD producer or buyer in the world and it dropped 95% in 6 months since the launch, the older projects like Storj are still unable to break over they 2018 ATH, and "miners" are dropping like flies with 8-10$ payouts a month for 12TB, whatever value they have is because of poeple desperately holding them, not because of utility.
What is going to keep your tokens valuable since you're constantly printing them?
Anyhow, you can't have uncensored free speech without abuse, you can't compete with a free platform when charging poeple money, and the majority of the poeple on this planet will choose the most convenient and easy to use thing over whatever else you promise them. That's why we don't have yet a YT/fb/tw killer and there are slim chances there will ever be one.
Oh, and one more thing, you don't need a blockchain to have a decentralized website, it's not a must, sometimes I think it's actually a burden.
