Takedown requests would need to be sent to the nodes holding the data or to servers holding links to the data. I don't think the dev teams or parent companies would have too much to worry about.
At a high level, the idea seems to hinge on "incentive to hold the data". Dealing with DMCA becomes a disincentive.
Filecoin's actually been around for several years. I think Storj is based off of it.
Ahh, thanks. Storj doesn't appear to support file sharing though, looks more like personal storage, which would make this less of an issue.
Edit: Might want to put 2014 in the title.
I think filecoin's even older than that though this site appears to be from 2014.
I believe that Filecoin is from early 2014, same as Sia and Storj.
Filecoin whitepaper came out a few months before the Storj one. Filecoin however is not functional, while Storj has been functional for about 8 months.
In that case, how are they dealing with questionable content and resulting DMCA takedown requests?
