Nevermind, I was able to find the conversation myself quite easily using Primal's advanced search feature. Vitor explained it exactly as I described it above: View quoted note → View quoted note → He explained it rather patiently, given how hard you were going after him about it, actually. Even so, after that explanation and the conversation ended amicably, you STILL didn't get it, because you STILL think it's based on mutes. It's not. It's only based on reports, and by default it has to be 5 or more reports (not 4) from npubs you follow, before a post gets covered by a warning, which you can just tap to show anyway...
