You can create unlimited addresses and then send amounts of bitcoins which are over the fee-less minimum transaction limit to your own addresses. That means you can technically spam the blockchain for the price of the electricity.

A transaction may be safely sent without fees if these conditions are met:

*It is smaller than 1,000 bytes. *All outputs are 0.01 BTC or larger. *Its priority is large enough (see the Technical Info section below)
