There’s no fixed number, but scraping too aggressively from a single account or IP will get flagged quickly. Instead of thinking in quantity, focus on how human-like your scraping behavior is. Spread requests out, rotate IPs, and avoid accessing too much data too fast.

You can, but it's riskier than before. Facebook detects automation patterns from tools like Puppeteer or Selenium, even in headless mode. If you’re using them, take extra steps to mimic human behavior by randomizing delays, using proper headers, and implementing session handling.

Yes, in most cases. Facebook restricts access to much of its content behind a login, and unverified or fresh accounts often hit roadblocks. Using an aged, verified account helps, but even then, login patterns and request volumes need to stay under the radar.

Yes, but only to an extent. They might work for simple tasks like copying visible data from your screen. However, for critical scenarios, they often fail with login walls, dynamic content, or anti-bot protections. Hence, we don’t recommend them except for surface-level scraping.

Facebook data is often used for market research, brand monitoring, lead generation, and sentiment analysis. Some also use it to track public trends, analyze competitors, or train AI models. However, usage must respect privacy norms and legal restrictions.
