There is no accurate answer to this but I believe that there are more unregistered accounts that contribute either because they don't have an account, or they have forgotten to log in.
As of February 14, 2015, there are more than 54,263,517 registered contributors on WikiAnswers. If there are about 1,090 supervisors, there are at least 54,262,427 registered non-Supervisors on WikiAnswers. Do note this count reflects total accounts as opposed to unique registrants.
Accounts named "IDxxxxxxxxxx" are in fact guests working under their IP address. Registered contributors may or may not also contribute using their IP address. Therefore, Answers.com accounts do not necessarily have "'ID' counterparts."
No, they did not.
WikiLeaks is in no way affiliated with WikiAnswers.

WikiAnswers does not provide information on personal bank accounts.
Wikianswers will not give out passwords to people's accounts.

Yes. WikiAnswers is now a part of Answers.com. All accounts that were created before the merging of Answers.com and WikiAnswers are still valid.
Brands can have account on WikiAnswers. Anyone can have an account on WikiAnswers. You cannot use WikiAnswers for spam; it is to be used to only to answer questions for people or ask questions that people may want to know.
