I doubt a fake coinjoin provides beyond minimum privacy. It is relatively trivial for a chain analysis company to figure out you're faking the coinjoin when the time comes and you'll have to consolidate most of the outputs you created by the fake coinjoin.
You'd be better off consolidating them in a real coinjoin using Wasabi Wallet, BTCPay Server, or Trezor instead.
Yeah, guys. You better off use flawed software that
merges outputs together and funds the operation of chain analysis. What a sham.
