What formats for proxies can be used in the scrapebox article scraper plugin?

The following formats can be used:
Url|Username|Password
Url|Username|Password|IP:Port
Url|Username|Password|IP:Port:User:Pass
If Url|Username|Password is used, a random proxy from the “Proxies and Settings” tab will be used when posting articles to blogs. If IP:Port or IP:Port:User:Pass is added, then this proxy will be “bound” to that specific account and will always be used for logging in and posting articles to that particular blog.
You can have a mix of accounts without any proxies and with proxies, account with proxies assigned will have that bound proxy used as priority else it will just use a random one from the proxies and settings tab
