@seveaux. Writing the history is essential. However, as in steemit case, It is still centralized in my opionion. The way of showing disagreement is still unhealthy.Although even your reputation lower, people will still able to see your post. As an example, Steemd provides the information of your updates.
The people who doesn't want transparency may not really like the idea of media blockchain. Everything is really transparent but let's say we are all having dark secrets at one point or another. But I agree with you at the point that transparency sometimes can get you into a real -life problem.
Thank you for speaking out your opinion. Cheers <3
