Excellent!

The only flaw I see in your plan is the fact that the US has made possession of some images a crime. So, if we post those images to the blockchain "in order to preserve them as evidence against the pedophiles," chances are that the blockchain itself might be destroyed as a result of law enforcement helping out "the elites" who tend to be the ones producing such filth.

On the BTC blockchain, this isn't as much of an issue. However, the STEEM blockchain has 20 witnesses, all of which could be discovered via court order and taken out.

Hmm, not all of them reside in the US's jurisdiction though.

Still, it's a risk I wanted to point out. They made it so that anybody investigating them for crimes against children, if the investigator had solid evidence, that the investigator would be jailed to stop the investigation.

It took me years to figure that out. It's the only instance where photographic evidence that a crime was committed is illegal to possess. And, it's not illegal for the reasons that they state -- it's illegal for purposes of defense on their part.

Of course it's also used for offense these days, now that computers have come on the stage, and are so easily hacked.
