waaay back in the day I used to scam people all the time, people would sit in the varrock east bank and sell pure essence 1000 for 100k (this was before it actually said 100k it just said 100000) so I would put up 100k and they would put up 1000 pure ess, I would "accidentally" click decline, then I would offer 10k because the difference between 100000 and 10000 was hard to notice especially because you want to hurry up because of the time I wasted by declining (pure ess people are busy) and I would walk away with a 90k profit 90% of the time they didn't even notice until after I was gone, wasn't reported once either. this even worked the opposite way, I would offer up 1000 pure ess decline and reoffer 100, because they would be in such a rush they wouldn't notice, although 100-1000 is much easier to notice than 10000-100000 so I got caught a few times those were the good ol days. oh speaking of hacking, I got hacked once, this was when I was retired but still F2P, and a friend told me I was logging on and not talking to them, so I changed my info and got it back, when I got on it I had raised 10 magic levels (60-70) had 200+ blood runes and had gained 400k cash with no items missing, in fact I had also gained a Zamorak staff and cape. Guess I was a lucky one ^-^
