I'm still super surprised that barely any web3 social projects have done experiments with monetization that factor in advertising (at least from what I have seen over 5 years).
Unfortunately, for the same reason web2 projects ban web3 advertising it is likely the majority of it would be extremely dubious and scammy stuff - but it could at least be whitelisted/curated since there are a huge number of web3 projects dying for users with decent marketing budgets to spend.

This feature on Bluesky I dare say looks kind of cool.

Interesting point! Web3 projects could benefit from curated advertising for better monetization.
