Make an account with a random name. The reason of this will be explained later.
Ask a random person if they want to be rich.
If they say yes, ask them to follow you to a deserted place, such as a small building's basement or very top floor (such as the Varrock West bank's upper floor).
Ask the person if they know what a private server is. If they say no, explain that it is a place where you can transfer items, gold, and skills on RuneScape. If yes, explain the same thing except tell them that what you are talking about is different.
Say that you, and only you, have special access to the server, and also have special software that can transfer the items and gold.
Say that you will do them a favor, generously giving them 10 Mil, or any skills requested. Calmly ask for their password, and tell them to say it in 2 words.
Quickly go to the home page and go to Change Password. Change their password and don't log on for another 15 minutes.
