Not only does the site reveal your personal information, but it also lists a number of cryptocurrency addresses that are said to be under surveillance. However, One of the Ethereum addresses specified under 0xa7e5d5a720f06526557c513402f2e6b5fa20b00 does not seem to be available.

There was probably confusion at some point in the chain of command and the Treasury wanted to blacklist 0xA7e5d5A720f06526557c513402f2e6B5fA20b008, another address.
Another vague possibility is that Russian hackers got early access to the wallets used by ETH 2.0. Cointelegraph asked Vitalik Buterin for a comment but it was either unavailable or we had the wrong address.
