Nope, Mixy is not the only one. The criteria where it has something similar to "money" and had advertised here but no longer did so was also shared by WW, and WW should make more sense, given it have more massive campaign and logically reached wider audience.
It cannot be whirlwind.money. This mixer relies on a multi-signature address as all deposits go to this address
https://www.blockchain.com/explorer/addresses/btc/bc1qf8h5k6sash8007vpesymxkw2xsg5d0r3j4l5vmcrwpz2pqu66fjstzgd3r The balance of this address is zero and it has not received deposits since July.
.money mixers are only Mixy and mixtura but mixtura didn't have an advertising campaign here.
