The Solana Foundation has removed validator operators from its delegation program due to their involvement in sandwich attacks on traders, where retail investors receive the worst possible price.

This attack involves placing orders before and after a pending transaction, manipulating asset prices for personal profit.

Validators identified via memepools, facilitating such attacks, were banned from future delegation work based on Foundation rules prohibiting malicious activity.

Solana (CRYPTO:SOL) aims to protect users from exploitation and uphold the integrity of its network by cracking down on fraudulent activities.
