For testing the proxies you can do on many web proxy checker but those are not idle most of the times.
Best tools which are not proxy tools specifically but those do have a built-in checker which does that part here are those:
GSA
Scrapebox
At last but important is that never ever use public free proxies for Social media and other important accounts because you will end up getting into trouble of getting those banned or blocked.
Always use Private IPs which works for that purposes.
Hope it will help you.
Basically banned and blocked are two things not oneBanned or blocked? Even if the website says that the proxies are okay to use with the social media site after testing? Private proxies are too expensive & I'm planning on using about 1000 accounts but they aren't my main
You can build a custom test in scrapebox to do this, if I understand the question correctly.Hi, how can I test proxies I scraped to see if they work with websites like twitter and other websites? Does elite proxy switchers paid version do this or scrapebox?
