I do not think this is a good idea. The new community wiki emphasizes this in its question text:
Each answer here relates to a different criterion which may (or may
not) lead to degree revocation.
As I put in a comment on the new community wiki -- I'm actually really concerned that the structure of this community wiki will be misinforming people who ask these sorts of questions. Mostly on these questions the top answer has been "no/we can't say/depends on institution". If people read these answers with an AND conjunction instead of an OR conjunction; or, take them as absolutely-enforced-at-all-institutions, then that will be misinformation. It also doesn't seem able to account for the vast differences in academic cultures around the world (link). There's no room in this wiki structure for the very best answer, "we can't say because it's very locale dependent".
Furthermore: The majority of the questions this is seeking to short-circuit are in the negative direction, i.e., usually about things you pretty much can't have a degree revoked for. Regarding the current question in this vein, the two highest-voted answers currently have kernels of:
Revocations on grounds of expression of (political) disagreement with
the issuing institution are unheard of in rule-of-law democracies.
I've never heard of such a case, although it would certainly have
become very well-known.
I sit on our university's Senate which is the body that would have to
deliberate a degree revocation. Even a straight-forward case of
plagiarism in a degree requires a long, drawn-out and surprisingly
contentious decision, and it might happen once or twice a decade. This
is the last step of a very, very long and drawn-out process.
These negative best-answers will be lost in the wiki structure looking for positive criteria for degree revocation. People still won't see an answer to the specific questions they're asking, and will continue to ask them.
I would suggest that a better "canonical" question for this purpose would be of the form, "How likely is it to get a degree revoked?", which can then deal with the central issue of it being extremely rare, in fact, a non-issue in almost all cases.
