Botters....

[Shougun]

It's plausible they have someone hitting enter in shifts (sounds like an RMT strategy). I cant do it all day, but I watch TV and just hit enter on my keyboard repeatedly for a couple hours. (you can complete a craft and also start a new one all with the same button - perhaps you could consider this an issue of the crafting minigame, could post there with some suggestions)

On a less wondrous note they may actually be bots (3 days straight is unreal, unless played by shifts of people); However, they are likely a low priority for SE since they are paying botters (low population - once larger, discriminating will be easier on their finances). Hacking is probably their top banning priority when it comes to application interference.

(Unless over extreme periods of time it would be hard to tell if a bot was crafting or if a human was crafting).

side note: This is the suggestion forum for website/lodestone only.

Other side note: I have no true idea what SE priority is, I don't represent SE though i'd like to ^_^ lol. It's just my speculation.
