All the communities on lemmy.lukeog.com are mirrors of Reddit boards. lemmy.lukeog.com does not accept posts from Lemmy users – only its bot may post and comment, and its posts and comments are just mirrors of Reddit posts and comments.
This doesn’t seem like a useful way to use Lemmy. It’s more like just a mirror of Reddit, in which case archive.is or web.archive.org would be more useful, in my opinion.
Better not to waste bandwidth and resources on this, in my opinion.
It seems odd to not even allow commenting, but I’m not seeing how this does any harm. If anything, I’d rather have access to it for those few situations where reddit is still the only good option to find what I’m looking for. Better than giving reddit any activity.
Plus, if this makes it easier to crosspost interesting content to local communities then I’d say it’s definitely a good thing.
