Although not immune to spam attacks, Grin is massively-prunable. Spent inputs & outputs can be removed from the chain leaving only ~100 bytes of data, making it 4x smaller than an avg Bitcoin tx( ~400bytes) and 20x smaller than an average Monero tx(~2kb) Zcash and Monero are particularly vulnerable to spam attacks because unlike Bitcoin, they can't do pruning: all nodes need to maintain a list of spent coins indefinitely. Bitcoin+CoinJoin+Lightning is much more scalable.
