Imo that's as much a problem of the sorting algorithm as it is with a single community blasting out too many posts at once without any consideration for how current frontends are unable to usefully integrate that into people's feeds. A couple of years ago nanoUFO was being a bit (subjectively) overenthusiastic about posting - I counted and !games had 40 posts at once from them and it made the first couple pages of my feed basically unusable for a while.
