Just found out about something terrifying. It’s possible to reuse the URL of a Bandcamp release and completely overwrite (including hidden page metadata) it with a new release.
This will only make it harder to track digital releases and shows how important it is to make a snapshot when entering a new digital release, especially Bandcamp.

And to make this post not too off topic: It seems the date when a Bandcamp release first was publicly available can be determined via the public_embeddable variable. (Still, care needs to be taken since it could’ve been shared privately via link before that.)
