Whirlpool was extremely easy to Sybil attack since the attack victims pay the mining fees to move the coins of attackers.
Wasabi's coinjoins require users to pay for their own block space, which aligns incentives to defend against attackers passively spying on rounds for free.
Emessbee also requires users to pay for their own block space. The mining fee is calculated after all change addresses are submitted, then divided up equally among all participants, and deducted from the amount that would otherwise go to users as change
