It seems that prestashop addons does not pass negative module reviews. I added a negative review on a module that didn't work at all on my site and the author trying to fix it for a month but no luck. Funnily enough 2 months have passed and the author of the module still has no feedback from me. Isn't this a violation of the free speech law? But five stars are listed with the author of the defective module.
