If you are the person who abandoned a tent full of crap at EMF: We are going to find you.
You have enraged a group of people who enjoy puzzles and suddenly have a lot of free time.
Run.
@jonty forgetting an entire tent and all my belongings after a highly social few days seems like exactly the sort of thing I’d do. Have you tried calling out to the nearby woods, or leaving out a pair of noise cancelling headphones and a copy of The Art of Electronics to coax them back to civilisation?
