Twitter has automated systems that find and disable abusive API keys in bulk. If you received a notice from Twitter about your application being restricted from write actions between 5/29/14 and 6/2/14, it may be one of a set of apps that were mistakenly targeted during this period. These API keys have since been reactivated and we apologize for the inconvenience.
Please go ahead and try to perform a write action with your app to confirm (you may not have received notice of the reactivation). If you are still prevented from write operations, please file a ticket and we will investigate the situation: https://support.twitter.com/forms/platform
