Latency arbitrage / price-feed exploitation.
Using delayed quotes, fast/slow feed differences, or any technical advantage to capture risk-free fills (including trading off stale prices).
Hedging to bypass risk rules (internal or external).
Opening offsetting positions (same or correlated instruments) across multiple accounts, platforms, brokers, or firms to neutralize drawdown/risk limits or “lock in” pass conditions.
Copy Trading between different account of another person.

Reverse / group hedging (copy trading between accounts to game limits).
Coordinating trades across accounts (your own or others’) where one account takes the opposite side or different sizing to manipulate daily loss, max loss, or evaluation outcomes.
High-frequency “tick scalping” / order flooding.
Ultra-short holding times designed to exploit micro-moves or execution quirks, including excessive order modifications/cancellations, “spam” orders, or behaviour that strains liquidity/execution.
Trade manipulation / abusive execution practices.
Any attempt to manipulate fills or platform behaviour, including quote stuffing, exploiting price spikes caused by illiquid conditions, using prohibited EAs/bots to exploit broker errors, or trading during known outages/glitches.
