Here's my contribution, a low budget, low effort process. For some reason, there's a local variety Bird's-eye that grows wild around here. And after witnessing a Crow once, strip bare a small bush within 5 minutes, i think i have a good idea to why it grows as a wild bush in these parts.
The only task i have is to harvest a chilli bush when the majority of them are a bright red. From there, they're kept in a colender on the kitchen bench to air dry (and tossed daily) over a couple of months. Well, that was the usual process in drier, less humid times. But since La Nina the last couple of season's, it seems to take around 6 months to dry properly. If this keeps up, i'll have to go back to drying them via the old brown paper bag routine.
Yet to sift out the bad ones..

I did have a crack with some Carolina Reaper's two season's back. But they only got to seedlings before stalling, and go toes up a couple of weeks later.
