Need advice on how not to get "trade hacked" (found a jah rune)
So something crazy happened this morning. Colenzo dropped a jah rune in a run and I got it. Funny considering I have to open inventory to pick things up. Anyway, after peeing myself and screaming in delight, I decided I want to trade it for ber (ber and ist is what I am trying for) so I can make a COH. Well, people tell me to watch for trade hackers. Known people who "trade hack" are all over me. How do I avoid this? What is it? All details are greatly appreciated. I never had a godly enough item to have to worrry about this stuff...
