Does the Steemit is always good?

So it's just my thoughts about the ways what can broke down steemit reputation.

If Steemit use blockchain principe and post can't be deleted or edited from a side. This can be used in a harmful ideas and deals.

In this way anybody can use the steamit like a storage and sharing of dangerous information like as how make a bomb, drugs, how organise terroristic attack and etc.

Also steemit can be used for sharing stolen data, like private photos, technical ideas what still don't have an patent, and claim for any profit.

As decentralized platform Steemit can be used to organise meetings and rebellion.

And one of more sadly part of this project what it's like a grow media for mediocrity what will nonstoppable create useless post and content and make blockchain of Steamit more heavy. What will kill the project over the time. No penalty post rules can stop it.

And if each time make the hardfork of the network for fix this type post also must destroy Steemit idea about no censorship platform.
