It's a good way to share your proxy lists on another resources. List size must be at least 100 proxies. Maximum size is 20000.
Make the list as private, access only by link. Or public, access to all users.
Choose advanced parameters, like:
Anonymity: transparent, anonymous, elite. Protocols: http, https, socks4, socks5. Timeout: 1000-30000 milliseconds.
And more. Also you can select the expiry date of proxy list.
You can separate proxies by countries, just select the option "With Countries", and list will be sorted automatically.
Select the "My Lists" page, hover your mouse over the list and click on "Trash" icon.
No, your proxies stays only here.
