An idiot statement like that could only possibly be made by a hypocrite admin, making such statements as if to encompass every admin is really stupid, it is also there server therefore there rules, Go figure that. And as you asked for my php script on this last week, you should know that any player on my server duping items doesn't get banned they just get called out in public chat when they join the server and everytime the script runs that they have x item in x quantity so everyone knows.
This games current state leaves very little choice for admins to use there server the way they want to, suffice to say if the dupe wasn't just fixed in the first place, this wouldn't be a problem, but its not, and so I will use it as it is really is the only way to have unlimited items without exposing creative to everyone on the server or the hassle of taking out items all the time etc. Until that is fixed this way of cheating will be used as it allows me to use a large stack of blocks without all the inconveniences of not doing so.
Option to have this inventory cheat check disabled would be better option.
