You can post to Mastodon and tag Lemmy community and the Mastodon post will appear as a Lemmy post.

There are significant limitations to this approach such lack of graceful support for thumbnails, markdown (doesn't work on the Mastodon side) and URLs. I.e. it's only good fat basic text posts (or image only posts).

Not sure exactly what the question is but I'm fairly sure the answer is yes. ๐Ÿ˜€ Anyone can start a Lemmy/Mastodon instance and anyone can create new software that federates with it.

My question is that since Lemmy/Mastodon are centred in Europe and hence is bound to follow the EU norms, can anybody create something similar to this - anywhere in the world outside of EU - and then federate it into lemmy/Mastodon ?

Not sure what you mean by "centred". They're both just software. Some of the developers certainly live there but they're both open-source projects with contributors from all over the world. And software doesn't have an originating country.

But software developed and working in the EU zone does have to follow certain regulations.

What does "developed and working" even mean? Both are developed using GitHub, which is owned by an American company. Servers are located around the world. Developers are located around the world.

[โ€“] Docker@lemmy.world 1 points 1 hour ago

Practically anybody is free to use GitHub. However, if l'm the developer, l need to comply with the laws of the country l live in/work from. The same regulations apply for the servers as well.

That's what I mean !! If I work from lndia and the server is located in lndia, then neither are bound by EU regulations pertaining to the internet/social media. At the best, the server would be barred from the EU.

What makes you think Lemmy is "centered" in the EU?

[โ€“] Docker@lemmy.world -1 points 5 hours ago (2 children)

Anything that doesn't go down well with the EU norms get banned immediately, sometimes the user too gets blocked.

Lemmy and Mastodon arenโ€™t centralized. Instances can federate with other instances as they choose. If your instance has, for example, a lot of bigoted communities and users, you can expect the bigger instances to de-federate from yours.

You can always federate with instances that reject โ€œEU normsโ€โ€”whatever that meansโ€”in a bubble of your own.

Where? I'm not on an EU instance. And you were recently directly linked to the fedecan initiative.

[โ€“] FartsWithAnAccent@fedia.io 6 points 6 hours ago

They are not centered in any location.

Now that WordPress has official ActivityPub support: yes, pretty much. Posting to both Mastodon and Lemmy will be a challenge, though, as Lemmy doesn't really offer following individual users.

Technically, any website can be an ActivityPub server, so you could "trick" Lemmy into thinking your website is a community while "tricking" Mastodon(-likes) into treating it like a normal feed. That's pretty messy, though.

If you mean the ability to post at both at the same time, on the same site, there's mbin.
