The fees.
So in Bitcoin, demand for block space is already high and the block space is limited, all a spammer can really do is drive up the cost of transactions, which they also have to pay to maintain the attack.
In Monero, there's the adaptive block size, which has a somewhat complex scheme but basically miners are incentivized to keep the block size down with a cost to raising it so they won't raise it until the value of the additional transactions outweighs the cost to raising it. So a spammer can try, but they'll only raise the cost of transactions for a time after which they'll not affect the throughput at all, they'll only raise the size of blocks. To continue this attack they have to keep fees high and increase the number of transactions they're doing, so they have to pay higher fees and more fees for more transactions.
In both cases these types of attack are very expensive.
