# CashoutGuard

> Fraud prevention for rewards, GPT (get-paid-to) and offerwall sites. CashoutGuard scores every signup, offer click, conversion and cashout, and flags multi-accounts, VPN and residential proxy users, emulators, spoofed phones, bots and offers completed too fast, before the site pays out.

CashoutGuard is a self-serve SaaS run by SSWAP MEDIA LLC (Wyoming, USA), hosted in the EU (Nuremberg, Germany). It has a small browser collector script and a server API. New sites start in shadow mode: everything is scored, nothing is blocked until the owner decides.
