I've noticed several addresses receive AND SEND tokens in Ethereum which have an uncomfortably large number of leading 0s.
 I thought all transfers had to be signed by a private key that corresponded to the Ethereum address owning those tokens? That's why I'm not sure how this happens.
I'm sure I'm missing something about my understanding of ETH, I thought all addresses that could spend their ERC20 token balance, had to have a valid cryptographic signature coming from a private key that corresponded to their the public address.
 Could someone give me a brief explanation of why this address is able to send the ERC20 token NMR, out of its balance?
Address in question: 0x0000000000000000000000000000000000028Ae8
 Additionally, I would like to know what is the longest vanity address that has been found to exist which was generated via brute force, or a clever vanity address finding algorithm.
