Polymarket Launches Anti-Spam Measures and Bans Ghost Fill Accounts
Polymarket has released a new feature update introducing a latency spam mitigation mechanism to ensure smooth order placement and cancellation for users, while also fixing the "insufficient balance/authorization" error issue.
The platform has identified and banned multiple clusters of ghost-fill accounts, all of which were created before the recharge wallet system went live; the new system will prevent the bulk registration of non-compliant accounts, and the core issue of limit buy orders is expected to be resolved in the coming days.
Polymarket enhances platform fairness and trading experience through technical optimizations and account governance, benefiting compliant traders and institutional users, while speculative accounts relying on manipulation and spam requests face pressure, improving liquidity and market trust simultaneously.

Polymarket has faced criticism for high-frequency trading and account abuse issues. This update continues its systematic iteration since 2025, focusing on addressing long-standing pain points such as order execution delays, error messages, and ghost fills.
In terms of capital flow, the platform concentrates resources on genuine traders through technical bans and recharge wallet restrictions, reducing the distortion of liquidity and odds caused by malicious volume manipulation, while providing a more reliable ordering environment for institutions and high-net-worth users, attracting more compliant funds into the market.
Similar to the governance paths of several prediction market platforms addressing high-frequency trading and multi-account manipulation from 2024 to 2025, Polymarket is currently in the mid-to-late stage of transitioning from early growth to mature compliant infrastructure.
Structural judgment: This essentially belongs to the reconstruction of the industrial chain. The platform shifts the trading environment from "manipulable" to "fair and efficient" through anti-spam and account governance, with mechanisms that raise the cost of malicious participation through technical barriers, concentrating pricing power and liquidity among traders driven by real information, accelerating the evolution of prediction markets towards mainstream financial infrastructure.

The harsher the spam requests, the harsher the platform governance.
Banning ghost accounts is not a punishment, but a way to return pricing power to real signals.
Whoever raises the cost of manipulation first will lock in a long-term liquidity moat.
