For example this comment: https://lemmy.sdf.org/comment/984558 and this post: https://lemmy.sdf.org/post/873681 I both deleted, however from other instances they still appear to be there.
In case of the post others can still interact with it (comment and vote) except me, OP. In case of the comment, it just keeps the original text instead of deleted by creator, it can be interacted with, but it is also accessible to me as OP.
This is how the comment and the post appear from lemmy.ml. Still there, alive.
Edit: As per other lemmy user, this is already a known bug: https://github.com/LemmyNet/lemmy/issues/3588

Known issue being worked on: https://github.com/LemmyNet/lemmy/issues/3588
For posts, I have been working on it this week and found that it has been broken since June 23 commit. Posts don’t even get removed on the home server with 0.18.2, a fix is already waiting for acceptance: https://github.com/LemmyNet/lemmy/pull/3613
As for comments, with 0.18.2 - it depends where the delete is done. If you are on a remote instance from the community, the comment will be deleted on 2 servers, but no more. The local instance you use will delete, as will the community home, but it seems to me there never was any code to distribute deletes to subscribed servers: https://github.com/LemmyNet/lemmy/issues/3625
It also impacts moderators removing posts and comments. As these internally are similar to deletes. !asklemmy@lemmy.ml is one of the communities that has a lot of moderator removals due to people confusing the purpose of it as a technical support forum, and you can see servers not getting the mod removals frequently.
