Your account could be shut down if any of the following happen:
Someone else places trades on your account
You log in from multiple unrelated IPs or locations
One device is used to access multiple accounts not owned by the same trader
You try to get around these rules using VPNs, device swapping, or trading on someone else’s behalf ("ghost trading")
Bottom line: one account, one trader. Trying to outsmart the system will get you flagged.
