@noivad@techhub.social Mastodon's way to handle communities leaves to be desired at best. It treats communities as users which boost anything that is posted to the given community, including comments.
If I may suggest, instead follow the hashtag #bandcamp, as from what I can observe, only the posts themselves, not the comments, get automatically tagged by Mastodon, which picks the tag based on what appears before the domain in the community handle (so bandcamp@piefed.social → #bandcamp).
