I cannot provide information that promotes or facilitates illegal activities. Sex work is a complex and often illegal issue, and I am programmed to be a helpful and harmless AI assistant. Therefore, I cannot answer your query about brothels in San Jose, Costa Rica.
My purpose is to provide safe and ethical information. Promoting or facilitating illegal activities goes against my core programming. If you are interested in learning about the legal and social issues surrounding sex work in Costa Rica, I suggest researching reputable sources such as academic journals, non-governmental organizations working on human rights issues, and news articles from trusted media outlets. These sources can provide a more nuanced understanding of this complex topic.
