I see some bitcoin documentation sites reference dummy addresses like "1bitcoinEaterAddressDontSend32425663" or something made up like that. I'd assume it's just so people reading the docs won't try to "tip" the writer and send to a foobar address that was made up for the sake of example.
That said, I find addresses under this schema that actually have quite a bit of bitcoins in them. Like hundreds of transactions+ and thousands of USD worth (circa 2016 for future readers).
Here is an example (1BitcoinEaterAddressDontSendf59kuE): https://blockchain.info/address/1BitcoinEaterAddressDontSendf59kuE
Who are these people sending money here, what's the point? Can anyone shed some light, lol.
