Elixir's really fun to do this in because the BEAM will let you have hundreds of thousands of processes sat around doing nothing quite happily, so slow IO and such is something it's weirdly well-suited to.

This is on my photography site so I'm less fussed about them harvesting my writing, and more about causing problems for image harvesters. I'm sure they'll get some stuff anyway but at least one bot got stuck in a 400 page hellhole earlier today so I'm overall very pleased :D
