When using the poster, if a proxy fails, will scrapebox attempt to use another proxy to post that comment?
When using fast poster for instance, if you are posting to a list of urls, and a proxy fails on any given url, scrapebox will skip that url. It will not automatically attempt to retry that url with a different proxy.
Part of the reasoning for this is that proxies don't give proxy specific error codes. If they don't work they can give the same error codes that a website url will give if it doesn't work. So Scrapebox has no way of knowing if it was the proxy or the website that failed. So if scrapebox kept hammering the urls thru different proxies it would exponentially slow scrapebox down in posting.
This is why its important to use quality proxies when posting, failing to do so can dramatically lower your success rates. Also you can always export failed and then repost to failed list.
