There are two problems with this:
* The set of questions is limited, and bots can be programmed to know them all.
* Even programmers might not immediately know an answer, and I can understand
  them turning away on that occasion (take for example the "name-binding" term).

This is impossible to find out, I think, since SF.net does not publicly show
real e-mail addresses, instead, each user has an alias [EMAIL PROTECTED]
