Then why don't you clone yourself? If you can't clone with an AR/Gameshark, all you can use then is the GTS, which you can do right?
I would've used an AR, but I never use it for unfairness. I'll never use a code that gets Pokemon illegally, or stats/moves illegally, or even items. All I use is AR only to clone, which many event collectors do (like myself) to make exact copies that are still legit so we can keep what we gave up since they are rare. If you cloned and checked it's legitness on an R4 and legitchecker, it'd say legit as long as the original wasn't a hack itself. But cloning is debatable, but mostly it is just all opinion. But cloning in any way is exploiting a glitch/holes in the game, and cloning does make an exact copy. You know ~RNC~ right? I saw her in your VMs, and you traded with her like shinies or something. Well, she does clone as well, and not with the GTS.
But OK. If you feel it is wrong, then fine. I was just trying to help you out. But seriously, clone yourself. Asking others to clone only with the GTS is giving them pressure to do it right, because it is their fault if they somehow lose the Pokemon while exploiting the GTS's glitch, which is not fair...
