The 'wait before changing info' advice is only treating the symptom. What actually flags a bought account isn't editing the bio - it's the handoff. That account has a device fingerprint, carrier, and IP baked in from the seller's setup. The moment it logs in from your phone, TikTok sees a completely different environment: different device, network, location. That mismatch alone looks like a hijack. The edits you make afterward just shine a spotlight on an already suspicious account.
Getting the original email helps with recovery but does nothing for the fingerprint problem. A few things that actually work: log in from a device that mimics a normal US phone with a real carrier IP, not a datacenter or VPN - those are easy to spot, and a bought account on a flagged IP is toast. Don't touch anything for a while, then introduce changes slowly, like a real person would. The seller telling you to wait is just buying time for the account to look settled on your device before you poke it.
If you're doing this at any scale, the device side is where most people lose accounts. I run accounts on rented real Pixel phones in US data centres (DistrictDroid) precisely because each one carries a genuine carrier SIM and a real US IP. That means a transferred account doesn't trip the device-mismatch checks. Emulators and antidetect setups fail here - the fingerprint is spoofed and TikTok reads right through it. Whatever you use, make sure the environment looks like a genuine US phone, or the 'surprise set feature' won't matter much when the account is gone in a week.
