No, but the difference is that in steemsmartcontracts you can define your own operations/contract functions, and things to do based on those functions. So you could define an function that, when you create the cooresponding operation, causes all steemsmartcontract nodes to go into an infinite loop or something similar.

Look at [this comment] for more details about how this vulnerability can be extended further as long as there are no computational fees.

the flags and reputation loss that would rain down on you for such an action.

You could use an account that has never posted -- even created through anonsteem because these transactions cost very little RC to avoid flags.
