…kinda?
They do federate, so that I can see reactions from other PieFed instances just fine. But Lemmy does not use the data for anything. It just passes it on for whoever can use it.
Yes absolutely. Not only are they federated, but they are even exposed via the API, as described in more detail at https://piefed.social/c/piefed_api/p/1596518/emoji-reactions-in-the-piefed-api. Of course it is up to each third-party app to decide how or whether to do anything with that, but it’s there whenever they are ready for it, and emojis show on the PieFed web UI.

This document is based on implementations of custom emojis in Pleroma, Mastodon, Misskey and Fedibird.
That said, I am not certain if they can all interrelate currently, as opposed to merely representing similar ideals. This should help get you started if you wanted to do more deep diving though:-).
Here’s a screenshot of how this post looks from within a PieFed instance:

The Fediverse is a interconnected network of social media instances. It has a lot of similarities with Reddit, but the communities are distributed across different instances, operated by different owners. This instance in particular is located in the Nordics, and acts as a gateway to the greater Fediverse, allowing access to read and comment on a wide range of content. Why not dig down in different Topics from the Explore menu, or register an account to personalize your feed. **Server rules in a Nutshell:** 1. No Harassment, hate speech or discrimination 2. No spam or otherwise malicious behaviour. 3. No Authorian or Facist propaganda 4. No Misinformation and Pseudoscience 5. No Violence and Threats 6. No Explicit Sexual Content or Exploitation 7. No Impersonation and Misrepresentation 8. No Illegal Content This instance is committed to keep hosting inside the EU, avoiding any US-based hosting providers.
