It's not possible to remove them. That's the point. They can't be removed. Can not.

Exactly. The only way to kind-of remove data from the blockchain is if ~15 (don't remember the exact number) of the top witnesses agree to do so. Technically, it's a fork then, and everyone's free to take the old chain and run with it. But at least the main Steem chain will no longer have the data.

PS: Good to see ya around!

Going to be an administrative hell hole if the witnesses have to continually address submissions on a case by case basis.

There are some times that I see the Steem application of blockchain being a really poor fit for social media. I really worry for the likes of dSound and dTube if they go mainstream.

There's not much debate really, blockchain is absolutely a poor fit for social media. That doesn't mean it can't craft a valuable niche for itself, despite its flaws.

Perhaps the best solution is a hybrid of the centralized and blockchain systems.

Can't witnesses agree in editing a certain block simultaneously? I know, it will never happen, but just hypothetically?
