You have a list of these freepers who have joined the LDS? Those that have left because of the truth being exposed here have spoken up. Like many other things LDS there is what you say and what is true, and they rarely line up.
Regarding the claim that people have investigated the LDS (or joined) because of these threads I have one word...
mentitur
For us, we have a list of those who left or decided not to join the LDS church.
