she will know who you may have seen if you write reviews. As KK said, as long as you see well-reviewed ladies and act appropriately, I don't see why you should not tell her your ID. It might help her screen you as wel, esp if you have whitelist referralsl. I know a lot of guys do not give out their handles, but if you are going to do a review of her, why not? If you act like a jerk towards her, I can see where you might be reluctant to disclose your handle, hopefully that is not your case.
