Absolutely.
I want to be clear that parliamentarians must take action to discourage this type of initiative. The question is how. The answer is up to you. Making decisions based on emotion may be good politics, but it does not make for good policies. It is important to find the right way to act.
In my opinion, increasing the number of signatures and imposing more restrictions on official agents are good avenues to pursue. However, I do not think we should prevent citizens from signing more than one form. We must also consider election workers.
