Here are the free proxies that I talked about before. I can’t guarantee that they’ll work all the time. I have it set up to add new proxies every 60 minutes. I’ll add some stuff to this page when I have the time. These proxies can be used for both scraping and posting. Keep in mind they aren’t as good as paid proxies. These are free and your results will vary with them. There’s a list for ScrapeBox and another for other tools.
Free ScrapeBox proxies here.
