@dansup@mastodon.social no, NodeBB v4 always reports activitypub in protocols, even if disabled. I can update that so it's dependent on the global switch, but it's still possible to have AP enabled but not have any categories federating.
I'm just wondering whether FediDB found the forums because content got federated, or whether there was some proactive nodeinfo crawling, that's all.
