Please don’t expect the community to give you answers to your questions which you then delete right afterwards. Those of us who put time into answering your questions are not doing so just to serve your personal needs, we are here to help build a community knowledge base that others can search and reference.
This has become a chronic issue with Lemmy and its starting to feel like it’s a waste of time to answer questions.
Fediverse is not private in any sense. Anything you post (or up/downvote) is blasted out to every federated instance and only gets deleted if that instance respects the delete command, which you cant rely on.
