Although there is no smoking gun pointing to the responsible party, the Libertarian Movement has complained about dirty campaign tactics including destruction of signs, threatening e-mails, a campaign headquarters in San Carlos spray painted black, and even fake flyers expounding attacking PAC in the name of the party.

Peter Guevara, brother of the presidential candidate Otto Guevara, said "We don’t know who is responsible, but come to your own conclusion. Which party would benefit by putting those who are in second place to fight amongst themselves?" 

Ana Gabriela Alfaro, Vice-presidential candidate, admitted "there is no proof against any one.  They only want to make it appear that we are involved in dirty campaigning to make us look bad, particularly since we are growing. We only campaign fairly!"

The flyer in question calls PAC the "neo-communist party" and that it belongs to "Extreme Labor Unions", it appears to be signed by the Libertarian Movement.
