If you mark nostr.fmt.wiz.biz as SpamSafe it will accept everything from that relay, because you are saying that relay is safe from spam.  If you don't mark it, it will only load notes from people you follow.  I can't tell if you marked it or not.

If it is not marked, and you turned on spamsafe, and then this event came in, that is a bug.

And there is more work for me in this area including:  feed filters to also do spamsafe filtering,  and having a WoT rather than just your following list.
