The majority of SQL injection vulnerabilities found by searching for unsanitized input at GitHub is by Portugese or Spanish users, especially in PHP. I am not trying to generalize, but it seems to me that a StackOverflow in Portugese perhaps is not such a bad idea.
Any source for this statement? I ask this because Portugal has a population of 10.5 million people while Brazil has 201 million people and both have Portuguese as the official language.
My statement may seem false if you only inspect the first pages. Though I seem to remember that the majority of the exploitable repositories were in fact Portugese or Spanish.
