I'd be careful with this though, lately I've seen that if you share a negative opinion about time travelling, time travelers seem to take it as a personal attack towards themselves for some strange reason. =(
I used to time travel in new leaf on occasion, but I've chosen to not time travel in this game. I think playing this game at a natural pace is a super relaxing thing. When I run out of things to do in this game, I simply turn it off and go enjoy some of my other hobbies until the next day. While I wouldn't outright call time traveling "cheating", I do believe it's manipulating the system. (what is what you are literally doing when time traveling). It can have some negative impacts on other people in the animal crossing community as well. Like posting up items for sale in the marketplace that the general player base doesn't even have access to yet, and trying to make a huge profit off of that. Or even posting up photos of your super advanced town and potentially spoiling someone on what is coming up in the game that they haven't experienced yet. When all is said and done though, I'm not going to be mean to anyone who time travels and it's really up to each individual as to how they choose to play their game.
