This behavior is as annoying as it is unhelpful. I agree that nobody should let the story fade from public interest but spamming random threads doesn’t accomplish that. It’s just obstructive and if anything it’s doing more harm than good. There is a thing called alarm fatigue. If you keep “shouting from your rooftop” you are just going to push your neighbors into shutting their windows.

Also maybe consider talking to a therapist about it? It’s none of my business but this level of investment seems unhealthy.
