How can i use proxy for survey work

Most survey and offerwall sites are very strict. Using proxies or VPNs can easily lead to bans. Even residential proxies are not always safe. The safest option is using your real local connection that matches your location and profile.

The real question truly is though, how do you mask fingerprint to make sure they cant track that you are multi accounting

Be careful with that. Most survey and offerwall sites are very strict about proxies and can ban accounts pretty quickly if they detect them, and a lot of proxy suppliers don’t even allow that kind of use case in their terms, so even if it works at first, you can end up losing both the account and the proxy service.
