That should be considered as bot and bannable in my opinion.
It requires constantly sending key press which some script, or putting something heavy on keyboard, anyway it's a hack. Isn't it ? I don't know other ways to keep running like that, if you dont press key character stops.
Repetitive actions should be banable imo, there could be some bot detection system.
Or suspected player could be PM-ed by GM, like they do in other games to check if it's a bot.
Having good stats on players activity is crucial for NGD to optimize server such that it's pleasant for all of us. Having players that cheat the stats, hurts us all.
The same goes to multi-logging from the same IP to dragon wishes, than one character or the other takes actions
but not both at the same time. Though this could be solved by allowing to enter portal only people who participated in invasion (this would be fair no matter how people would cry about it).
