Proxies for Scrapebox

Today I have bought Scrapebox and I was curious about the 16 proxies I received with it. I heard that it is possible to use his own. However, yet I didn't purchased any and so I wanted to know will I have problems using these 16 proxies I received or do I need to buy some new one after a certain time has passed?

you can get @proxygo proxy service for harvesting purpose.

And get Private proxies for posting purpose it will works best

How do you like Scrapebox so far? On the fence, thinking about getting it for research, but there's an alphabet soup of tools out there, many of them look really, really good.

Well the Scrapebox tool is great and has very high potential. My problem right now is that its telling me when I test my 10 private proxies that they have Google passed, but once I start harvesting I receive 304 and 302 errors?
I didn't harvest for Costum footprint stuff, just one word keyword on Wordpress and even then its still not working on Google engine. Works on yahoo...
