You may be correct, and I bet you know more than I do about blockchain.
I did stumble upon the phrase 'immutable blockchain' which makes me wonder if there is redundancy in it.
I do not comprehend what prevents a blockchain from becoming mutable in principle.
The whole idea of blockchain is to run an immutable trustless ledger.
Allowing later modifications to older blocks would essentially make the whole idea pointless. It will then require "trust" in those who can change the historic blocks.
Simplified: a new block validates against the previous block, if a previous block gets changed, all subsequent blocks become invalid. So changing old blocks would also require rerunning the whole chain from that point on.
Technically this would only be possible if all "miners" (in case of steem witnesses) were in on it, but even then, copies of the unchanged blockchain would still be available. You would basically create a new chain all together.
Some trust in a big enough majority of reliable people (Which most of Steemit's top 30 witnesses are) is crucial for the sustainability and efficiency of a blockchain which should become mutable, or else.
I'm not sure how to do this just right, but one of my followers brought to my attention that you investigate people on the platform who aren't on the up and up. This is a post I did yesterday that might interest you...

Thanks! Yes, that's what I do ;)
The kinds of offers like you describe in you post are becoming more and more common. My best advice to anyone, don't go for service offers that are brought to you in any such manner. Only use services that you can see are working!
I'm going to keep writing posts to warn people... The devs and admin won't do anything- so I don't know what else to do. I've been monitoring his wallet and people are falling for it. I got another message this morning.
Stay vigilant! Unfortunately too many users here are gullible or inexperienced and the sheer amount of scammy operations, phishing attempts and abuse in general seems to be hard to control.
I've been there! That's how this account came to life!
And top that off with a litany of upvote and follow beggars! "It's like Facebook but you get paid!" I figure they'll go away eventually when they don't immediately get rich- but for every one that leaves 6 more seem to take their place... Ah- what's an honest guy to do???
You keep doing the fine job you do... and I'll keep my eyes open and warn as many as I can!
