If someone started a rumour that “the_optimist on HN sleeps with seventeen goats every Thursday” and you started getting calls of people saying “you’re a pervert for sleeping with seventeen goats”, it would be quite obvious what motivated the call, would it not?

Before calling something impossible, consider the bare minimum effort to skim the linked article, or read any article on this subject. It is in fact quite trivial and provable.

Your hypothetical is neither trivial nor provable.

How does one identify the “first mover”? How does one identify the integrity of the “calls”? What if the calls are a single caller represented separately? What if the calls are falsely represented by motive?

What if I, in fact, have today received 400 calls on the matter you have stated? Am I eligible to sue you?
