RE: Censoring visibility is not removing from blockchain, my thoughts
Yes, this is a real problem. I don't know how often criminals use the Steem blockchain for their terrible aims, but currently there would be no way to erase such posts completely.
Affortunately, this blockchain only saves text data, and the pictures it shows are hosted in other services, not in the blockchain itself.
If the authorities take that decision, they can force the hosting provider to erase those pictures from its servers, and in this blockchain will only appear the link to the erased material. I guess that would happen if the case is so bad to need the action of law agents.
If the problematic material is not a picture but an information... there's no solution. That text would remain there as long as the blockchain exists.
hi @spirajn
i didn't know that. Where are all those pictures being stored if not on blockchain ?
This is insane. So steem is only partly decentralized?

Exactly. It's like @djennyfloro says. If we copy the link of the picture above, we can see this:
https://steemitimages.com/0x0/https://files.steempeak.com/file/steempeak/djennyfloro/NmxUuriN-falloxbow-1058032-639x266.jpgSo, when we upload a picture in Steemit, it is saved in the servers of
steemitimages.com, infiles.steempeak.comor any other front-end. The Steem blockchain only saves that link to the image.Yes, it is partly decentralized. When those servers fall down, your pictures disappear.
Hi @crypto.piotr,
If you look at how it is when you insert a photo, you see that it's an external link in bb code. Where the photo is stored is clearly identified by the full link to the photo.
It's never been hidden, and as spirajn just mentionned above, it might just be a blessing in disguise in case there's problem with the photo such a pedophilia, or illegal pornography.
hello @spirajn,
Thank you for that thoughtful answer. I haven't personally seen such content on steem, however, after seeing the news on TV about a case in a forum which was taken down, I was wondering what would happen if something like that happened in Steem.
It is also a question I've had from the deputy (a member of the French parliament who is thinking about the blockchain) I met, which was wondering how to protect people in case of criminal use. And I was unable to answer him.
Oh, I've just remembered that there is, in fact, a feature by which pictures and other multimedia are stored in a blockchain, even here. First I thought that the problem you pointed out belongs to our future, but that's not true, because we already have the IPFS. It is really a "multimedia blockchain".
I vaguely remember that Busy was already using the IPFS protocol for its pictures, but certainly Dtube gives the option to upload the videos to it. I'll explore a bit more about this.
