2/ Spammer can hire real people to farm accounts
I think this idea might work if we
- create reputation graph, where valuable contributors vote for others and spread reputation
- users can fine-tune their reputation graph, so instead of "one for all", user can have his personal customized graph (pick 30 authorities and we will rebuild graph from there)
The cost for this service is likely keeping up with ID systems for multiple countries, infra and support.
Potentially, if this is made into a protocol, it can be decentralized kind of like the SSL system, so each country manages it's own rules.
So we need a mechanism that makes this identity verifiable, maybe you get a unique identifier from the identity service, so you can block the account. There is no mechanism to report you to say, the identity service (this is a bot), so you manage your own block list.
The risk here is fingerprinting, your id can be cross referenced across apps. Maybe here is where you implement a zk proof that you're who you say you are.
You've identified a problem that unrelated systems also have. Like banks and identity theft. This solution isn't responsible for causing that problem.
