Why would anyone want that? The Fediverse is a social network, which means that interactions between individual users are possible. With mirrored posts, such interactions and, above all, communication with the author of the post are not possible. In the worst case, such mirrored posts are simply spam.

PeerTube has that built in. You can set up a channel and have it import or mirror a Youtube channel. For Lemmy there's several bots and scripts. As other people said that's what lemmit.online is about.
Be a bit careful when rolling this out. Several people don't like it. They've left Reddit for a reason and this is drowning them in bot activity. And usually these posts are low engagement, Reddit users can't see the comments, so you're not getting a lot of answers. I think it's good practice how we here have separated that to dedicated instances, so users can just have genuine conversations everywhere else.
Yea, bot posts screw up our posts:comments ratio
They make a ton of posts but we don't have enough commenters to hit all of them. What few comments they do get are spread out across different posts so there's no back and forth conversation, engagement dies.
and seeing a bunch of posts with 0 comments or OP not responding causes users to leave Lemmy
Yes. And I've seen people do really weird (and worse) stuff, like re-post questions. And if you're unaware of that, you're bound to take 10mins out of your day to answer the product or Linux or life question and later find out you were ripped off. At least that's how it feels to me if people fabricate that kind of activity. And it kills the mood to write comments for a while.
Thanks, I didn't know Peertube had a built in tool for mirroring a channel. I will look into that.
I just found out about lemmit.online from the other answers and I agree with you on having be a different instance is good practice.
Alright. And for your information, the Peertube function is a bit broken. I think the Peertube developers did their best. But Youtube has a lot of datacenter IP address ranges blocked. And they do rate-limiting and force people to sign in after downloading a few videos. Plus yt-dlp (which it relies upon) and Youtube are playing this cat and mouse game... So it's disabled on most instances because it doesn't really work. I was able to make it work on my instance, but I had to jump through several hoops. Configure a SOCKS proxy and tunnel it over my home, residential internet connection. And I think I transferred my login cookies because some videos would be age restricted.
That's what https://lemmit.online/ is for reddit to Lemmy, https://sr.ht/~cloutier/bird.makeup/ for Twitter and apparently also Instagram.
One problem with this is copyright; if it's OC images or text posts, it could infringe on the original poster's copyright. Not a problem if it's merely sharing links.
Thank you for sharing the links and for pointing out this has potential copyright issues. I think its still good to have these tools though.
The main problem with that is the lack of communicating with the OP. The only place where that is negligible would probably be peertube/YT. Especially since YT is one of the worst with 3rd party frontends, so fully mirroring might just work better (ignoring any laws, that is).
Lack of communicating with OP would be nice but its nice to just mirror their page if they are content creators
Mirror? What even for?
I don't know if it's good or bad, but it seems that most people forgot about https://alien.top/ and https://fediverser.io/
