That's what I wanna know!! I was thinking maybe there is a specific person/persons that get the denunciar complaints and carry it out afterward. Seeing as how when you click the denunciar button there's a "comments" section. There would be no need for comments if someone wasn't leitura them right?
Here are my three possibilities I've compiled in the procurar for the answer to your question: 1) Not enough people reported. 2) The person reviewing the reports reviewed the user being reported's history and website's contribution and decided that the user wasn't that bad. 3) The infamous fanpop glitch.
