I think they just get marked as deleted, and what is supposed to happen is that the deleted comment gets picked up through federation and the destination server should delete their local copy. Sounds like that isn’t happening between Lemmy and Mastodon.

I also noticed that whenever you delete a comment, with the Liftoff app on Android you can open a menu of the deleted comment, click “Nerd stuff” and still read what the comment said. This means that the contents of the comment are never actually deleted. It’s simply tagged as deleted but the content is still there. I think you can currently only counteract that by editing your comment first, then removing it.
I read on raddler that this is actually a privacy consern, the post are not actually delete just hidden, post link raddle.me/f/lobby. And I guess there should be delays in deletion across instances anyway since it is not centralized?
Edit: I found a longer explanation , link: raddle FAQ
Raddle’s strong privacy-focus and activist roots would make this a tricky proposition as federation depends on pushing user data to a multitude of different servers controlled by anonymous and often problematic (far right) people.
Rather than being decentralized as it’s often advertised, federated technology distributes data to a series of centralized servers owned by individuals with varying ethical beliefs, goals and motives. Anyone can set up a server and then fetch user-data from other servers to their server, giving them control and ownership over other people’s data and allowing them to use it indefinitely in ways the people may or may not approve of.
Furthermore, the federated technology currently in use in software such as Lemmy doesn’t really allow users to delete their own data. It lives on forever on all the servers its pushed to, creating a privacy nightmare and even serious legal issues due to the EU’s “right to be forgotten” laws. These laws are violated when the operators of the social media platform deliberately mirror all user-data to countless servers in perpetuity, even after it’s “deleted” by users.
In contrast, Raddle allows users to delete all their data from our server with a click of a button. Our server also doesn’t store the IP addresses of whitelisted users to further improve security.
Our users tend to heavily prioritize control over their data and have shown little interest in Raddle taking their posts and comments and deliberately pushing them to other sites they may or may not want to be associated with.
so raddle is part of the fediverse but not a lemmy instance?
No the are not part of the fediverse, at the moment, mostly because of the privacy issue described in the faq. I think they are open to it in the future depending on how they solve the issue. But they are not commercial either, so they have no inzentive for ads or other company policies. Raddler is just one part of postmill, just like lemmy.world is one part of the fediverse.

Nothing is ever deleted. Just create a new unrelated username and whatever you do, don’t use your real email address for sign-up.

It’s best to assume everything you add to the internet is never deleted. That is the much more likely scenario.
I think that it just takes longer to spread the change across whole fediverse. On the home instance it would appear to be deleted, but it needs be propagated everywhere later.
There is no guarantee that the delete request reaches all other instances as there is no kind of synchronisation protocol. If that delete request never reaches the other instance for whatever reason, the post stays online.
I see and I understand that. Thank you for the correction.
