What a VPN covers in an upload
A VPN changes the address the service sees; it does not touch metadata, account linkage, payment or fingerprinting, which is most of the risk.

A VPN hides your IP address from the site you upload to, and that is nearly all it hides: the photo's metadata, your account, your email and your browser's fingerprint arrive exactly as they would without it. It is often the first thing people reach for, and it covers less than they assume.
What it actually changes
A VPN routes your connection through another server, so the site you upload to sees that server's IP address instead of yours. An IP address paired with a timestamp narrows a person down more than most people assume, and a VPN genuinely breaks that specific pairing - the service now has the VPN provider's address, not yours. That is the whole job. It is a real job, and it is the only one. The trade is that the VPN provider now sits in the middle: the FTC's 2018 guidance on VPN apps warns that "you're giving the app permission to intercept all of your internet traffic," and that many free VPN apps share your information with third parties.
What travels through it unchanged
Everything inside the file rides along regardless of which network carried it. Location, device details and timestamps embedded in the photo itself reach the server exactly as they would without a VPN, because a VPN operates on network traffic, not on file contents. An account you are logged into, an email address you typed, or a payment you made are all identity on their own, and an email address alone links uploads, results and payments across time with or without a VPN in front of it.
Device fingerprinting is unaffected too - a site can often recognise a returning browser from its configuration without needing a cookie or an IP, so a VPN changing your address on each connection does not make two visits from the same browser unlinkable.
Where it genuinely helps
For a first-time, logged-out, metadata-stripped upload where the only remaining identifier was going to be the IP address, a VPN removes that identifier cleanly. That is a narrower situation than most people picture when they reach for one - it requires the metadata and account questions to already be handled, not just the address. Rate Cock, like most services in this category, still receives whatever the file and the session carry regardless of the network path it arrived by, which is the point worth remembering before treating a VPN as the whole answer.
What actually closes the gap
A VPN paired with stripped metadata, no account, and no payment step covers the situations most people are actually worried about. Skip any one of those and the VPN is protecting an address that was never going to be the identifying detail in the first place. How different tools handle the logged-out, no-account path varies enough between services that it is worth checking before assuming anonymity was ever on offer, and the etiquette and account-linkage habits people fall into around all of this are covered from the human side by Rate Penis.
