I would say that our first tool is when we hand out press cards to those who apply to become members of the FPJQ. As I explained earlier, we have criteria, specifically to abide by our code of ethics.
Of course, people also have to work as recognized journalists. We check that. It takes a little less time to check someone like me, because I have been there for a very long time. But for new applicants, we will check the type of work they do. Do they work as journalists? Is that their principal occupation? I understand the reality of freelancers, of course, but if a freelancer also works in, say, a marketing firm, that might become a problem.
We have criteria like that. We issue, or do not issue, press cards, which are, in a way, a seal of credibility. That's more or less how we control things.
