Is it allowed to read the data dump of a closed SE site into one of the Stack Exchange site models listed for example here and use it as a base of questions to start a new Q&A site (or continue the closed one) outside the Stack Exchange network?
The first legal problem with this which comes to mind concerns the correct attribution of the content. In the licence.text file that is contained in the data dump it is explained that one has to
- Visually indicate that the content is from our sites in some way. It doesn’t have to be obnoxious; a discreet text blurb is fine.
- Hyperlink directly to the original question on the source site (e.g., https://stackoverflow.com/questions/12345)
- Show the author names for every question and answer
- Hyperlink each author name directly back to their user profile page on the source site (e.g., https://stackoverflow.com/users/12345/username)
To fulfill point 2. and point 4. this answer says, that it is enough to refer to the closed Area51 proposal.
Are there other legal issues that have to be considered?
