AmiiboGAF just shot themselves in the foot.
I don't know how much the rest of you know about LINE (I'm an expert), but amiibo and friendship are huge parts of it. It's not like it is in the thread where you can become successful by posting about how bad LINE is. If you talk smack about LINE even though it's accepting and public, you bring shame to yourself, and the only way to get rid of that shame is repentance.
What this means is AmiiboGAF, after hearing about LINE, is not going to want to purchase amiibo for themselves nor others, nor will they purchase any of Nintendo's games. This is HUGE. You can laugh all you want, but AmiiboGAF has alienated an entire community by separating.
AmiiboGAF, publicly apologize and cancel the LINE groups or you can kiss your community goodbye.
