Since we email you based upon what is in the email we receive, and not through FT, disabling that option will not make any difference to whether mods email you or not.

I think you forget we are volunteers, who fit this role around our other lives. Many of us deal with reported posts while we are on the move. I rarely respond to the originator of a reported post anyway, unless I feel there is a reason to do so - asking me to then log into FT to send that member a PM just makes it less likely they'll get a response from me at all as trying to move from email to PM on a smartphone is only slightly less painful than sticking a sharp stick in my eye.
