Real, and your diagnosis is right – platforms link accounts by fingerprint and shared browser state, not just IP, so a VPN on one machine does nothing for you. What you need is genuine isolation: every client gets its own environment with a distinct fingerprint, and cookies, cache and localStorage never touch each other. An anti-detect browser does exactly that, and the site compares them by real features rather than marketing claims. For an agency, prioritise team functionality – role-based access and a shared profile library, otherwise staff will pass logins around in chat, which is the bigger risk. Test on two clients before migrating all fifteen. Most have a free tier.
