Daniel's right on anonymity.
If you state your name and cong, I think the difference here is what kind of question is asked. If you ask something that is not common knowledge among the r&f but something people generally find out through apostate sites, they will report you to your elders. If you ask something about blood fractions or something, they will probably respond, depending on how the question is asked. They will say also 'why do you not ask your congregation elders?' (Instead of wasting their time)
