This day of creation caused a huge fall in party hats and many people who hadn't even dreamt of them were now able to get one. The prices are currently at the skies, but without this day they'd most likely be a lot higher. The reason for duping dragon items was simple: they had the highest high alch value and could create some serious money in no time. It's easy to say now, but Jagex was rather slow back in then. Just by taking servers down and doing a small reset (like jumping back 1 day) they could have stopped the amount of certain items rising. It took them several hours to fix the bug and few days to ban all the accounts the dupers had logged on. There's still rumours of some accounts avoiding the ban, tho.
Normal players who had gotten free/cheap hats weren't banned, even tho some merchants probably hoped so. Some wiser merchants noticed it at the early stage that something was wrong and sold their phats, some suffered probably the biggest loss in whole RS history. Even many top players went nuts from free party hats as we can see some of them even trading the dupers and begging for free ones. Probably the same would happen today too, but it still makes me laugh to see some of those pictures.
Here's some bank pictures and pics from Varrock during that "event".












Moneywise they wouldn't be THAT superior in these days, you gotta remember how more money comes to the game all the time. However if even one of those banks would have been saved, we'd have the richest rs player of all times without any doubt. You can also imagine what would happen if same kind of a bug was found and abused same way in these days. I bet many merchants would go pretty mad

Here Jagex first informs that something is going on and then states the holes have been filled.

In this picture they are clearing the air a bit. They promised a free full life time membership to the one who gives the information to stop this thing. It's been rumoured that some of the dupers informed them and got banned after that. Even tho some are still in nowadays complaining that Jagex lied as they banned them, in my eyes it was the only real thing to do. After all member accounts can get permanently banned for breaking rules and that if something was against the gaming spirit.
