what they liked before they followed
Give a follower and the account they followed. spark finds the moment of the follow, then surfaces the followed account's posts the follower had liked in the run-up to it — a vague portrait of what, exactly, earned them a spot in the feed. The tipping-point signal sits close to the follow, so it looks back a couple of months by default; widen it if you want the deeper history. Read straight off the public network — no login, nothing written, nobody's permission needed. For the full picture of two accounts — every like, reply, quote, mention, follow and block both ways — see dyad.
