I've only ever been scammed once. I had been playing for about a year and chopped willows for a week to save up for a rune scim. I bought a rune scim from a guy, and then i looked in my inventory and saw a iron one. I was pissed, but after a while, I realized it wasn't that bad. On another note, a few days ago someone was standing in Rogue's Den begging for more than 5 hours asking for 100k and said he lost his bank of 50m. I'm pretty sure he could have made way more than 100k doing something productive, and also trained some of his skills, enabling him to make more money in the long run. So when things don't go your way, remember that bad things happen to everyone, and being upset won't help. However, learning from the experience and looking to prevent it from happening in the future will help.
