Summarize the situations where everyone might get banned while using Alpha:
1. Transferring within Binance accounts, or funding without going through a third-party exchange to start trading; it is recommended that friends with multiple accounts withdraw to other platforms and then transfer to their other accounts; some users may have transferred internally a long time ago, or someone may have transferred to them, and they might have forgotten;
2. One device with multiple accounts, using scripts;
3. Multiple accounts under one IP address; currently, it seems that having three accounts under one Wi-Fi is fine, but we don't know about more than that;
4. The vast majority of reasons are the above points; if it's not one of these issues, it could be that the second-hand phone has problems, or it was registered on Binance before, or other reasons. Using a VPN will not get you banned; due to some activities on Binance requiring a VPN, you won't get banned for that. I often run around with different country VPNs.
5. If none of the above issues apply, just appeal, and generally, accounts can be unbanned.
