@phocks @mom101 @neilhimself I've been plugging away at a different issue on this (parsing likes, because my Twitter account was almost purely a content ingestion machine). As part of this I have discovered that it is possible to get a guest token for the Twitter API, bypassing the need to sign up for a developer account. I might take a crack at DM identification next - however, I don't have any sample data yet (no DMs in my personal account, now waiting on the archive for another one).
