user9313: Some time ago I started wondering: what if we create a new coin and use its Blockchain to store a website content?
Bitcoin is P2P, that way it is almost impossible to block bitcoin. Everything in the ledger is public and saved for eternity, would be good for some subreddits which were deleted recently.
What if the mining process would be just making backup of already existing specified social media websites?
Are there any similar projects, which could be used as a base?

user12983: 
Nobody will waste his disk space for storing blockchain.
Nobody will spend money for mining blocks.
It will be very easy and very cheap for dishonest person to "doublespend" such currency.


user9382: @amacilin's answer pretty much nailed it. But I wanted to counter a few such assertions /r/Bitcoin often makes about decentralised being better than centralised.
Recently someone said something to the effect of "Blockchain based storage/websites is the answer to the centralised server solutions, which have been around forever"
The thing is, centralised services have been around forever because:

They work
They work very well
They're cheaper to maintain

I know this isn't the question you asked specifically, but I thought it prudent to answer since often the excitement of "can it be done?" trumps "should it be done?.
It's also pretty prudent to question how moderation would be done. Even if if you're a staunch anti-censorship/moderation supporter, I don't know how one would ever sort through the crap without needing some moderation. 
Essentially what I'm saying is the "issues" with centralised servers are probably not worse than the problems with using a decentralised service. And this isn't even considering the privacy implications!

user26857: You're looking for Freenet, a p2p plataform which is only different from your idea in the fact that, to avoid wasting disk space, Freenet deletes old and unpopular content.

user2116: you might be interested to know that the bitcoin blockchain can already be used to store arbitrary data. for example the original whitepaper pdf that satoshi wrote explaining how bitcoin works has actually been uploaded to the blockchain. it was done using 948 outputs in a single transaction for a fee of 0.596175 btc ~ US$143.02 at the time i'm writing this. the whitepaper is only 180KB so the blockchain is not that cheap of a storage medium...
