Imagine Mallory (fake name), a nasty Avalanche competitor, wants to damage Avalanche reputation. She buys 200,000 AVAX OTC, spawns dozens of low fee (0%, 0.1%, 1% etc) validators with long duration (10, 11, 12 months), collects lots of delegations from unwitting delegators. They happily proceed with the delegation, forget about it and plan to come back after a few months. When she collects 50M AVAX in delegations she turns her many nodes off, all at once. Since Avalanche has no slashing function, she won’t lose her 200,000 AVAX. Unfortunately all of her delegators will not only lose all rewards, but their AVAX will be locked until delegation ends. Avalanche will suffer a reputational loss, while delegators will lose money and liquidity.
