AnonymoX vs Private Proxies for Social Media

Any thoughts on using AnonymoX for IM campaigns? I'm mainly using multiple accounts in Pinterest to drive traffic to my sites and currently using shared private proxies that seem slow. I just discovered AnonymoX as a FF addon and find their connections to be much faster even if I'm just using the free service. Other than speed, the difference so far is that I get to use different IP address every time I log in an account. I'm not sure if that's a flag that could get my accounts banned.

Please enlighten me.
