Is there an easy way to purge a Lemmy account or do you have to edit/ delete each comment and post first?

I’ve had issues with deleting posts previously and just resorted to editing them to be useless instead.

And risk burning yourself when the rubber wears out in 3 years and bursts?

Nah, get yourself one of those oat-filled microwavable teddies. Does the same job but with less risk of severe burns and doesn’t need replaced every few years.
