How Can I Use Scrapebox With Proxies

I have about 30 private (or semi-private) IPs, but anytime I use them I get an Error 503. That means that Google banned the IPs. Does anyone know what type of setting I need to use on scrapebox to avoid the ban?
I use only the keyword scraper and URL harvester.

Test the proxies in Scrapebox's Proxy Checker. If they pass and you're still getting banned it means that you either:

A) Forgot to tick the box that tells Scrapebox to use proxies
B) Someone else burned through those proxies

I tested them, and they are all alright. I also tick the box to use proxies.

I doubt if someone have used those proxies because initially, they would have harvest URLs. Then when I try them again I get Error 503. Then 24 hours later, after the ban have been lifted, I can use them again for only 1 harvesting before I get Error 503 again.

Sounds like they are being overused. Rent your proxies (private), they are only $1 a month if you buy several. PM me if you want to know where I get mine from, I won't advertise them in here.
