I think it’s good to encourage those who still have reddit accounts to migrate their content over here in anyway they can before deleting their account entirely. They may have content that they can post that would be beneficial to keep but starve that content from reddit.
It’s the strongest weapon you can unleash against that cesspit of a platform. New content is being made here daily and it’s amazing, but we have a way to go to compete with such a goliath content farm.
Saving the important posts, posting the question and answer to lemmy and then deleting those posts imo would be the most optimal solution. At least the information is available somewhere and not punishing people looking for answers to their queries.
