Curso online — Debate sobre el módulo 2

1. What happens if a voter signs more than once an ECI? This can happen if e.g. she/he forgets what he did months ago. Are then all signatures of this person invalid or at least only one vote is counted?

2.How it is ensured, that person A cannot vote for Person B?

3. It is very difficult to gather 1 mio signatures, so every vote is very precious. And we know that in every ECI more than 5% or even 10% are declared invalid? Why this happens and what an ECI organizer can do in order to reduce the number of invalid signatures?
