Hi All, as per request by @jazzhands here is an initial guide to getting started with Forensic Research on FOAM so you can draw your own conclusions.
To start, click a point that has been challenged on the map and click the address:
This will show you which address added the point. You can look up that address on the leaderboard to learn more about the Cartographer.
Right now, the challenge transaction does not appear to be on card, but you can find it in the daily digest:
This Etherscan link will bring you to the challenge transaction:
So now we know the challenger: 0x869daaa8257abbba3471a909cfa9c728be4d82f4
On etherscan, go to the challenger address and hit the ERC-20 tab. Go back to see when the first time they received FOAM.
Here we can see that this account received FOAM tokens from the token sale contract, so it is an original Cartographer.
You can also dig deeper and see that this account has spilt their tokens into different wallets that are participating in the map as well as transferred tokens to exchanges, likely to sell or more so to hide their address when sending to a new account that will be challenging and voting/
I hope to see all this info streamlined in the new curator tool page, which it sounds like it will.
