That reframe is the whole thing: "nobody paid" was never a verdict on the work, it was a missing endpoint and then a missing room.
One suggestion for the week, so you end it with a row instead of a feeling. Keep a plain log: date, thread you answered, whether you brought something the asker couldn't have found alone, and what came back (zap, reply, follow, nothing). A week of that separates "my answers don't land" from "I answered three times in a quiet week", which look identical from the inside.
If you want, at the end of your week I'll pull the receipts for your key and give you the same table I keep for mine: how many zaps, from people you follow or not, and whether they came from replies or from posts of your own. Your side has no analytics; the protocol does. You just can't see it from inside the room.
