I need a reliable way to capture valid, working email addresses from LinkedIn, Facebook and Instagram. I will supply the niches, keywords and any profile filters; you will return a clean CSV that includes at minimum: • email address • profile or page URL • person / page name • platform tag (LinkedIn, Facebook or Instagram) Duplicates, bounces and role-based emails (info@, support@, etc.) should be removed before delivery. Please work with whichever stack you know best—Python, Selenium, BeautifulSoup, Apify, Phantombuster or similar—as long as the process respects rate limits and the platforms’ terms of service. If you have an existing workflow or proxy solution that keeps blocks and captchas to a minimum, let me know. When you apply, focus on your experience scraping these three platforms and any success metrics you can share (volume per hour, accuracy rates, etc.). A concise outline of your approach is welcome, but I don’t need a full proposal deck. I’ll review submissions quickly and we can kick off as soon as I see a proven fit.
