A: Hi! The scraping limit depends on the type of account. With free accounts we don't recommend going above 50 per day. With a SN account I did 300-ish per day.
If you don't need emails or extra info, just the names of profiles you see in your Linkedin Search or Sales Navigator search, you don't need a scraper. You may just use a free extension from Closely https://chromewebstore.google.com/detail/closely-email-finder-li-d/gdhhcapaofinjmlambmbfhkicbpmidbn
