Here it is! Our metalhead.club public advert in Wacken! Thank you very much @MountainWizard for checking it out! If you're in Wacken today or in the next few days: Find our advert at Hauptstraße 33 and maybe take a selfie? 😉 (are we the first Mastodon instance that has publicly deployed an advert?) #woa #wacken #metal #metalheadclub #festival #mastodon
