Hi, We develop some very powerfull proxy scrapper. In first palec we mantain (updating each 3 minutes) a database that counts each succesfully and each failure of each proxy, so we can keep the best and discard the one's that fails a lot, as oyu can see in this image: We have almost 30k of proxies listed by succesfully connections. Our software is able to filter by countries, continents, etc. It can also get the fresh Google based list (usually arround 1k) and/or the fresh elite list, that havent being included in our database, because are fresh. The software can create a .txt file and even upload it to your server (to use it easily with GSA 'per example) This lists are perfect for use with SEO tools like GSA. Is not allowed to make public the list that the small and fast software create and/or updates every X minutes. Its for your own privated use. We are about releasing this as a very cheap monthly suscription (will be about $12 per month more or less) and we need BETA testers.
