Which private proxies service do you guarantee? What can you offer?

I have tried a couple proxy providers that didn't work well with Swagbucks, Swagbucks usually ban me within 5 days, so far I am just making loss, So I have been wondering if someone can guarantee me a service that won't be exposed to Swagbucks and providing multiple subnets from different locations in the US.
Thanks in advance.

doubtful anyone can say with 100% certainty you will never be exposed

by saying guaranteed i meant something with high anonymity to swagbucks cause they blacklist most of the proxy providers, at least these i have used are blocked by them.

We can provide whitelisted proxies that work on Swagbucks (http://ghostproxies.com/plans), but you need to make sure you're using 1 IP per account.

3$ per proxy .. okay, I will consider your offer if nobody offered a better one.
