(proposed new terminology)
A bump-and-grind regime is one which does not allow access to its deepest functionality without disclosure of background and purpose.
On a Q&A site, the deepest functionality is asking a question. (Other, less-deep, functionalities are answering a question, commenting, voting, and bookmarking.)
An example of a bump-and-grind regime is any ‘Stack Exchange’ site.
