Wikipedia defines integrity as the quality of being honest and having strong moral principles. Or as I have learned from real life mentors, it is doing what is right eventhough no one is watching.
I know habbo is a game, but I believe that eventhough it is a game, we should still have integrity while playing it. Like following the 15 minute rule even though everyone in base seems to be afk or asleep while on the red thrones. It is as simple as not making an alt, or tons of alts, and bring them in base to work and get more arrows/pay, no matter how subtle or low-key it may be.
Having integrity shouldn't only be limited to real life stuff. It should be demonstrated while playing other online games, it is being fair to other players.
If someone else "cheats" during a game, why do you need to cheat as well just to get the advantage? If everyone is doing it, doesn't mean you should do it too.
Don't sacrifice your integrity over a game.
