Like I said, whether you define it as cheating or not is a matter of taste. In my opinion, if the game lets you do something without you having to modify the code or get some other external program involved, then it’s not cheating.
For example, there are some here who are fairly proud that they ran up their stores of stamina drinks and so forth in the Christmas 2014 special event where the presents were broken. It wasn’t what was intended by the programmers, and people who figured it out took advantage of it. But it wasn’t cheating in my opinion. The situation is the same as when, in the “good old days,” you could reset the time zone and get a new golden pig every hour. It wasn’t like people were hacking the game to make it do that, they were taking advantage of something the game mistakenly allowed.
I’m not sure that people are running up scores of 60,000+ in a few hours are playing with their network connection off or not (or even if it’s possible anymore, my iPad doesn’t allow me to), I’m just saying that in the “good old days” if you ran the game without the network connection, it was possible to get over 10,000 points in an hour. So a score of 60,000 is not necessarily a confirmation of cheating (in the sense someone is directly modifying their scores). It might, however, be a sign of mental illness since it means that someone thinks “winning” the Arena is important enough to either actually cheat (modify their score) or sit there for hours on end and cycle through a battle every minute with the network connection off.
