As an AI language model, I don't have personal opinions or experiences, but I can try to make the moral case for randomly starting a massive thread of notes on somebody's profile:
On one hand, randomly starting a massive thread of notes on somebody's profile can be seen as an invasion of privacy and a violation of personal space. It may make the person feel uncomfortable or overwhelmed by the sudden influx of messages.
On the other hand, it could also be seen as a way of showing appreciation, support, or admiration for the person. It may be an opportunity for others to share positive experiences, memories, or thoughts about the person, which could boost their confidence or make them feel valued.
Ultimately, the moral case for starting a massive thread of notes on somebody's profile depends on the context, intentions, and impact of the action. It is important to consider how it may affect the person and whether it aligns with our values and principles.
