It looks like these other Bandcamp account are the official ones, because they link back to the Stones Throw and BBE pages:

https://jdilla.bandcamp.com/music

So the one from my OP is definitely suspicious. If ?uest or Dilla's people are lurking this might be something to investigate, in case the wrong people are profiting off this.
