I understand that your bots work for your use case, but it actively harms mine, and I’d happily call it spam.
I call it spam not because the content being mirrored is low quality, but because there is little to no community interaction on the posts. I’d I wanted to just read news, I’d just go to my RSS reader. The only reason I use Lemmy is because I want to see others’ opinions on the posts.
By the way, this isn’t me saying that it would be better if it had bidirectional bridging. If that was implemented, Lemmy would just be the second class way of interacting with Reddit content. I don’t want that.
Also, I use the All feed for discovering content, not because I don’t know about 3rd party community search tools, but because I don’t know what communities I like. The All feed allows me to find new communities that interest me, and I wouldn’t be able to find those communities just with those search tools.
