The only mod that I know of that has mentioned a gender is 29 and she said that she was female.
Have any other mods mentioned a gender to you?
I think that there are probably mods from both genders, but I would venture to guess that there may be more female ones.
In any case, if there are mods of both genders, it seems to me that it’s preferable to have male mods with female posters than the other way around. Could be “שררה” issues here.
(don’t worry – I’m half-joking. The half that’s joking is that I don’t think it’s assur; the half that’s not is that I would think that given the choice, that way is in fact preferable).
