If I type thousands of addresses on this website with my naked IP, what will happen? How will they know if I enter my address, your address or someone's address?
In overall, it's a basic rule to mask your IP address and take some security measurements to not leave your traces everywhere. Everyone should do it when they enter their address on blockchain.com, blockcypher, blockchair, mempool and other blockchain explorer websites.

So it will perform blockchain analysis on your address. And you are keen to hand over your bitcoin address (alongside your IP, browser fingerprint, and other identifying information) for
ask for it to have analysis performed on it?
This project will not become popular and I think blockchain analysis don't build their hope on collecting important data from this website but if they put something like this on major blockchain explorer websites, it might attract many new people to type their address with their naked IP.
