You know, Ayan said the exact same thing, Qami. Yes, I do mind >.>.
What people tend to do is play the game first legit without cheating, and then hack to get real teams faster. I did the same thing. I didn't trade hacked Pokemon, mind you. People like to trade hacked Pokemon because by getting rid of a disposable one, they can get a legit one back, with saves them the effort.
Turtwig, PokEdit doesn't give you bad eggs or anything, it just gives you custom Pokemon via WiFi. And AR doesn't give bad eggs unless you breed bad Pokemon. There's normally no way to tell if their clever about the way they do it.
I don't see anything bad with hacking personally, if they want to battle with hacked but legit mons, let them. They're not doing anything really bad. trading can be different, but I'm not sure.
