Scammed on RuneScape.?

Well, I got scammed on RuneScape because I believed a person that doubles money. Of course, I gained their trust by giving them 1k and they returned 2k, then I gave them 42k and they logged. But it was okay, because I made that with one trip of yew logs. ANYWAYS, I was wondering how to make a quick 2m without.... 1. fighting anything 2. it has to be in f2p 3. No woodcutting (because of all the botters, I don't get many logs) THANKS, YOUR ANSWERS ARE APPRECIATED! ~
