How to avoid interacting with poison or dust transactions?

I have so many dust transactions worth nothing and poison transactions worth a few dollars each that try to trick me into copy and pasting their address.

For tax purposes these transactions can be ignored when it comes to tax reporting because they were unsolicited and deminimus. But that is only if you dont touch them.

My question is dont they automatically get co-mingled with your wallet balance, meaning if you sell ethereum from your wallet theres no way to tell if you sold those unsolicited transactions. And if you sold them then that means they are taxable.

Is there a way to prevent your wallet from adding those transactions to your wallet balance? Or does everyone just concede that spam transactions become taxed as income?
