You can generate a 1MB block with only free transactions in it and it will get accepted (maximum block size is 1MB, although the standard bitcoin client will never generate blocks larger than 500K). @p{par}

The problem isn't the pool payout@p{--} the problem is that people participating in the pool end up with wallets full of tiny (e.g. penny-size) transactions.  When they go to spend those tiny transactions, they're bundled up together to make a transaction that is small in value but large in size. @p{par}

Pools can mitigate the problem by requiring larger minimum payouts (e.g. 1 BTC instead of 0.01 BTC). @p{brk}
