Hi Bruce, You can delete a campaign by setting its status to DELETED, but you are correct that there is no way to completely remove a campaign from your account. As for how to handle name conflicts, we generally recommend solution #1. You don't need to add a timestamp to the campaigns as they are being created, only as they are being deleted. Having many deleted campaigns in your account will not impact the performance of the AdWords API, and if you use the campaignStatuses field of the CampaignSelector then you can can ensure that deleted campaigns are not returned in your requests.
