There's nothing like that that's preventing it being listed.

The community was started 2025-01-19 17:37:24 - less than 4 days ago as I'm writing this. The bot gets it's data from a crawler, so there's a bit of lag, but not much - it's got about 3 days of data on it.

It needs 7 days, because it works by taking a rolling average of the previous 7 days. You'd see some crazy results if it started publishing results earlier. Doubly so because that community hasn't really grown organically, and has benefitted a lot from Fediverse drama.
