Because we are discussing legality, I want to point out that you just aggregated and published these links, the developers of the OpenBazaar software did not. So if a crime is being committed here, which of you is more likely to be committing it?
Does OpenBazaar do this? Probably not.
Are all these people anonymous on IPFS?
Probably somewhat because they're behind VPNs or proxies, at least that's what I hope they do if they're offering things like above.
Will this stop law enforcement?
No, it will not: https://www.theregister.co.uk/2017/10/08/vpn_logs_helped_unm...
You should also be informed that DMCA is not relevant to over half of your links. Its target is copyright circumvention, not narcotics sales etc.
The individuals allegedly selling those possibly illegal things could receive legal actions like DMCA and narcotics laws, and even you might for linking to them. But I was not talking about those individuals, only the irony that you are at greater legal risk than the OpenBazaar developers.
History disproves your disingenuous comments.
The most important issue is that OpenBazaar is software and the other was a service based around a website.
Why do you comment so confidently and enthusiastically, when you apparently understand so little?
