Well there is even better way of collecting ice flowers but as ernilos said, they already did so even long time ago because I was the only one to do so and I was getting banned all the time, most of the time it was CoMa or Team Manager/Admin. Now many kids are using this method because someone published my way of collecting them. As someone said above, it is better to just use ShowNPC etc. than NoDelay etc.
Well I would say it can be a benefit for the economy in the game as the cost of ice flowers will drop. What I know many kids are doing this when many players are online which in some cases brings CoMa or Team Manager/Admin to have a look at logs. My advice for those who cheat on flowers, only do so at night - at 1 to 5 am as less players would be on Act 4 as many players like me don't like bots/cheaters who have an impact on us - when I want to collect some flowers.
