This made me think, nope any kind of censorship is a slippery slope...but can we ban spam....? Meaning most Steemians see commercial advertisement as spam...like what tries everyday to flood your email account.
That being said, I feel you are correct to say, if it does occur. ..it will not work on a decentralized platform for long...it will fade away and be put in the lower cabinet where you keep the Ronco pizza maker...
As always thanks for the intelligence brief.
