Banned from gifting cars?

Sorry if this is in the wrong area of the forums or anything.

Somehow my gamertag has been banned from giving cars away for about a week, and I’m wondering why that is and whether there’s a dev here that can tell me. Did y’all think I was hacked because I bought some GNX’s specifically to tune and give away? Was somebody offended by the harmless calling card on the rear bumper? Was the feature not intended to be used that much and you haven’t yet gotten around to instituting a daily or weekly limit of giveaways per player?
