Frequently
Asked Questions

A VPN hides a visitor's real location and identity and lets them rotate through clean IP addresses, which slips past rate limits and geolocation blocks. Fraudsters use that to create multiple accounts, take advantage of regional promotions and pricing meant for other markets, and get around location-based restrictions. It also lets someone who has been banned come back from a new IP address and evade the policy.
