Personally, I don't mess around with any sort of hacks or custom content or anything... on any game, actually. I had bad experiences with it in Sims 2 and I just haven't touched it since.
That being said, I certainly don't judge anyone who has them! They definitely look neat and would definitely be convenient. Back before I was coming online and connecting with other players I had, like, three star fragments, only because I got lucky and had one meteor shower. If I didn't occasionally visit other people's island during meteor showers IDK how I'd get them.
And my thoughts on "cheating" are- unless it directly hurts someone else (like, say, cheating to beat someone in a race or something), who cares? Play how you wanna play! Like I said, I don't use hacks, but I do TT and some people get nuts about that, too. Like, I saw custom designs for "anti time traveling" signs. Like... why? Are you reminding yourself not to TT or something? Or just trying to potentially make visitors uncomfortable?
