I feared you all would come to this decision about clones. While I wholeheartedly disagree with your decision, I guess I'll have to live with it.
Two things, though, my sister and I both play myvmk. Due to real life being an issue she isn't always able to participate in quests. If I do a quest on my account and then switch over to hers to do the quest for her, does that constitute as breaking the rule even if the prize remains on her account?
Second, obviously those 60k people aren't all going to come play vmk, but let's say 10% do, that's 6k more users that are going to want stitch, princess hats, infernos, etc etc, how do you plan on addressing the limited supply of items with the surge of players? Any user that has these items will be able to ask for literally whatever they want because demand is going to drastically increase with the supply remaining the same. You're basically going to destroy the already flimsy economy if you don't have a plan in place.
