ATA you ban people for giving out their personal information such as phone number, location and name( 3rd party apps) yet you ask people to use their Facebook/Twitter/Instagram and comment on your profile with their gamer tag, their privacy is at risk and people can now stalk these people since they know who they are in game and in real life. This will lead into a massive cyber bullying. Could you imagine this, some people take Farming issues beyond what's it's really worth and make death threats. Now having their personal information on hand, woosh, watch this go out of hand quickly.
You're contradicting your own rules and praising breaking of privacy in exchange of gift that no one really knows what are the rewards. Is the gamble really worth the risk of losing privacy? Copy pasting this in case ATA delete this post.
