Ask Jeeves used to have two elements...the electronic/computerised one that still exists, I believe, and the human one. The latter was exactly like AnswerBank in that people asked questions and other actual 'people' answered them. The owners suddenly decided to shelve one half of their operation and the idiots dumped the human half!
I had provided literally thousands of answers there, more than anyone else in fact, but - despite appeals from us frequent users - they refused to maintain an archive of replies. Accordingly, each and every one, in effect, simply floated away into the ether when they pulled the plug. So, only if AnswerBank goes on "for ever and ever" will our answers be thus banked, I'm afraid.
