There’s no discussion or interaction on the bot posts. And if you subscribe to them they tend to overwhelm your feed quickly. And your Lemmy experience becomes akin to someone just sharing a bunch of article links. That’s the opposite reason I used Reddit or come here.
Lastly questions being crossposted are really dumb. Imagine AskReddit or AITA where your comments aren’t read by anyone, much less the person posing the actual question.
Cross posts with Reddit do exist and they are completely pointless.
There are a couple entire instances that consist of nothing but Reddit cross post communities and there is no interaction. They are almost not even a part of Lemmy proper.
