Is large scale direct reposting of content from corporate social media healthy for the Fediverse?

I can see if accounts do it occasionally and organically but are accounts that exist solely to repost popular and recent posts from twitter/reddit/Facebook healthy for the Fediverse?

There’s a way to do it, and there’s a way not to do it. If you’re reposting something that directly solicits feedback and you don’t know enough to be able to respond, that’s no fun. If you’re looking over reddit, carefully selecting interesting content, and hosting good conversation about it, that’s very healthy. Given you’re using words like “large scale” and “direct,” I assume you mostly have the unhealthy kind in mind.

I do because there’s a bunch of accounts that are posting a ton of posts a day straight from Reddit.

Like three hundred a day.

I struggle to imagine a way one could create 300 posts per day that would be healthy.
