I think a sports instance would be great for this reason. Starting with the next major release of Lemmy, anyone would be able to block the whole damn sports instance and be done with it. Though as far as I know, the sports communities are spread throughout different instances, so it won’t be that easy.
There’s not. I’m really into hockey, for example. We have a “hockey” community, but there’s also a community for each team. So 33 communities for hockey alone.
Though as far as I know, there’s only one bot that posts scores of hockey games, and it only makes one post a day and posts all of the scores as comments under that daily post. Then it edits those comments to keep them all up to date as the games are played. I wrote that one myself, and I specifically was trying to avoid spamming with tons of posts, as there can be as many as 16 NHL games a day.
