If you are a lightning wallet dev, stop allowing users to specify memos in invoices. If you must, maintain a description of the payment that's just saved locally in your wallet db.

Chain analytic companies, exchanges, and governments are taking advantage of this.

You wouldn't use AOPP to verify an address for an exchange complying with VASP/FAFTA bullshit, don't sign custom messages with your lightning node by being tricked into creating what seems like a simple invoice & memo and handing that to an exchange.
