Yes, I think I get this. In fact, in order to *filter* something, you have to *look for it* My node sees a provably unspendable op_return output from a TX and depending on the threshold, currently 83 bytes or less, sends TX to other nodes. But it has to *look* to see if its 83 bytes..... What if someone shows up at your work/home and starts playing a horrible + illegal video/audio of something? Most likely people would *look* realize its terrible and throw the guy out, call the cops, shoot the guy..... Is the person then at risk of *looking* at said illegal thing? What if its an email attachment? or an OP_Return data blob? Seems like logic and common sense would prevail in these settings.
