If we prevent these transaction from going into our mempools doesn't that prevent or delay these spam transactions from being mined therefore discouraging the spammers?
Yes, in the sense that when you configure your node to have a more strict mempool policy than that of its peers, it will not add offending transactions to its mempool, and therefore also not relay them.
However, each node makes at least 8 outbound connections through which transactions are relayed, and listening nodes can even have more than 100 connections. A single peer announcing transactions is sufficient for a node to hear about them, so it is sufficient for about 10% of nodes to relay transactions for them to reliably reach miners that want them.
In conclusion, your node might not be participating in the relay of such transactions, but the relay of offending transactions is only prevent if almost all nodes on the network participate.
