I think at least some people do not watch every episode that is released ASAP, so having multiple threads for multiple episodes that are released at once is useful for not spoiling the latter episodes, so that’s not spamming IMO.
That said, even on Reddit where there were more users, those multiple-episode-at-once (or whole series-at-once like netflix) animes tends to get lower discussion participation, especially the episodes in the middle so I understand where you are coming from.
Perhaps wait and see what the rumored upcoming 40x0 Super cards will be like.
