I think it is okay to do this for Txs that are of a bad monetary nature
For example, if someone creates coins outside of the mining protocol, I think it is okay to burn the newly created coins and block such a tx from happening again
I also think that if someone creates a spam tx, it is okay to make their outputs unspendable and bloc such a tx from happening again
But that's what I think. What do *you* think?
