How to get the IDs of one's tweets from a #Twitter archive, sorted by date, oldest first:
「(for f in data/js/tweets/*js; do tail -n +2 $f; done) | jq -s '. | flatten | sort_by(.created_at) | .[].id'」
Now I only need a tool that goes over this list, and deletes them over the course of about a year. I might add a bit of randomness too.
