The best way to get these accounts out of the game is by reporting them in game to jagex. While you have good intentions by letting us know about this over the forums, this isn't the place to report about the situation. Also thank you for removing the actual username of the link!
It wouldn't hurt to warn surrounding players to not go to the link/website when you see it in game.
Most of the time, the accounts that advertise those phishing sites are throwaway accounts which means they're easily replaceable. It's a constant battle unfortunately but those accounts DO get investigated and banned.
Keep reporting, your reports do help!
