stake-based decentralized moderation for social media

Hello,

I'm interested in decentralization and I'm working on the architecture of an anti-censorship social network with distributed moderation.

The main idea are:

– Messages are stored off-chain, while their hashes are anchored on-chain to guarantee their integrity.

– Any user can report content by placing a stake in order to discourage spam and false reports.

– Each report is reviewed by a small, randomly selected panel, chosen based on reputation criteria and link with trusted identities to limit Sybil attacks.

– If the report is deemed valid, the reporter recovers their stake and receive a token reward, while the panelists are also rewarded.

– A progressive reputation system adjusts dynamically user rights (stake requirements, access to certain actions, etc.).

– The recommendation algorithm would be open-source, with the possibility for users to choose between differents feeds.

I'm not building anything yet; I'm mainly looking for critical feedback:

Any blind spots or flaws in the design you see?

Any obvious economic or security issues?

Are there any similar existing projects I should look into?

do you think a such system could work in everyday social media usage ?

Thank you in advance for your feedbacks.
