About using SuSocial, I found that their email extraction feature is indeed useful for small-scale scraping, but it gets expensive for larger lists. A more cost-effective approach is to use a combination of publicly available tools like Hunter and Email Finder, which can help you build a list of emails associated with a specific hashtag or account. I recently extracted over 5,000 emails from a single hashtag using this method, with a validation rate of around 75%. For larger projects, it's worth investing in a custom solution, such as a private Telegram contact or a bespoke scraper, which can provide more accurate results and better handling of anti-scraping measures.
