First:
Go here
Second:
Under proxy type "SOCKS5"
&
Under anonymity "High"
&
Under proxy speed "1300 ms"
Third:
Click the button "Show"
And copy-paste 2x as many then you "need"
So if you're running 10 bots you would want 20 proxies, the more the better.
This is the way I get proxies and most of the time, they are pretty good.
