My personal feeling is that reddit repost bots are actively harmful to the growth of the fediverse.

In my opinion there's a few general buckets of users: link consumers, comment consumers, commenters, posters. Reddit bots help the first group, and actively deter engagement by the others. When your feed is a flood of reposts and no comments, the community feels dead and you're disincentivized to comment yourself. If you do comment because you don't realize the OP has no idea what lemmy even is, then you're even less likely to comment in the future.

I honestly care less about appealing to the link consumers, since they're just lurking and not helping grow the community. We could potentially do something like refederate but add it to everyone's instance block list by default, but I struggle to see the value in that for the handful of people who might unblock it. Otters idea of just having the communities be hidden unless you're subscribed, might be a reasonable approach. (We haven't really played with that lemmy functionality yet)

I'm also curious about lemmit's future as old reddit is locked down. Eventually reddit is going to start blocking however they're scraping.

That being said we consider our instances to be community led, and we're always are open to changes that the majority want.
