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.
Having a bunch of posts taken from another site with no real interaction with OP or anyone else isn’t driving traffic here, it’s boring the people who come here for discussion. The actual user posts will get drowned out by the huge number of reddit scraped posts. If something is interesting and fits a community here, post it. But scraping reddit to lemmy isn’t really helping as much as it might seem.
