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.
