There are some legal issues we need to take care of before launching the site:
GDPR - we need to protect the user data to the maximum extent possible and users need to be able to request a copy of their data and users must be able to ask us to delete, rectify or restrict use of their data.
Copyright - this depends on where we’ll host the site, in the US we must provide something compatible to the DMCA, I don’t know how the legal situation is and will be in the EU, especially after the new copyright directive.
Furthermore we need to take care in copying contents from Stack Exchange if that is the way we go.
Trademarks - ours and possibly from Stack Exchange
Data security should be a primary concern during database and architecture design. I think the GDPR requests could be done manually in the first few weeks (if there should be any), however we definitely need someone taking care of that, especially in legal matters. It might be a good idea (although not neccessarily MVP) to develop a request framework, where users can do most of the things themselves.
Same goes for copyright and trademarks IMO. I think it might be useful to develop a tool to submit DMCA takedown notices and to publish a list of them on our site, the same way that Stack Exchange did initially, however that shouldn’t be MVP.
We definitely need someone with legal experience!
However, with the other concerns, what do you think about them? Which of the solutions should be in our MVP, which can be added later?
