What it means is that I don’t accept the block, or any transactions in it. If you’ve paid me for something and your transaction only appears in an invalid block, I won’t credit you for your payment. If I’m running an exchange and your deposit only confirms in an invalid block, I will reject your deposit. As a miner of invalid blocks you won’t be able to sell your block reward on my exchange — or on any exchange which is running a non-mining full node. ie. you most likely won’t be able to sell your block reward on any exchange.
