eBay Seller Hub links sessions to IP stability, device history, and managed payments verification — similar rigor to Amazon but with stronger emphasis on seller performance metrics. Multilogin isolates each eBay account in a Mimic profile. Cross-listing agencies link eBay with Etsy and marketplace accounts via CMDB — never share profiles across platforms.

Profile hardening
- Mimic engine — consistent OS preset since account creation
- Sticky proxy for full session (sticky vs rotate)
- Warm profile: browse eBay as buyer before Seller Hub login
- WebRTC off or proxy-aligned; DNS through proxy
- Fingerprint audit before bulk listing automation
Automation boundaries
| Task | Automation |
|---|---|
| Login + 2FA | Human on production accounts |
| File Exchange / bulk listing upload | Playwright post-login, rate-limited |
| Order report export | Queue worker with lease |
| Promoted Listings budget changes | Manual or semi-auto with caps |
| Managed payments / bank / tax | Never automate |
Cross-listing agency pattern
Same SKU on eBay + Etsy + Amazon requires three Multilogin profiles minimum — US agencies: US CMDB guide. Inventory sync via profile pool manager with marketplace filter.
