As we are going to get more and more of these, them swamping the list of approved consumers will be annoying. There is little reason anyone would be curious about them. Maybe they should not be visible at all, but at the minimum should be filtered out by default from Special:OAuthListConsumers and Special:OAuthManageConsumers/approved (but not Special:OAuthConsumerRegistration/list). Probably Special:Log/mwoauthconsumer as well.
