<p>With all these reports of people receiving spam through dust transactions (e.g. Enjoy Sotchi, Bitwars etc) what would be the implications of setting a minimum transaction amount on the network? Why would anybody wish to send 1 Satoshi (0.00000001 BTC) it seems to have almost no economic benefit? Would such a limit disrupt any legitimate activity on the network?</p>

Should there be a minimum transaction limit to prevent dust spam?
