If anything, shouldn’t it be encouraged, and even automated? I’m including even the ‘old’ stuff from reddit here. Reddit shouldn’t be the absolute owner of the content submitted by users. When I migrated here, it wasn’t because of me being against reddit users, but being against reddit the company. Copying the content here actually hurts the company in sense that they don’t get to then gatekeep the crowdsourced content.
Because automated reposts just drown out all the posts that people are actually participating in. Yes you could scrape reddit and repost all the content here but lemmy doesn’t have the userbase of reddit so your feed would just be full of a bunch of dead bot made posts.
But if a person deliberately reposts something from reddit in a Lemmy community where it fits and adds to the community then that’s perfectly fine.
