A editor of a newspaper is generally well known so why not announce who the editor is from the start? Each person then PMs their report directly to that person (copying MITO in so he can see there is no cheating happening).
Mafia could convert that person but it would cost 65%+ of the starting budget to deter that action.
Why not just kill the editor?
It also depends who else is a known innocent e.g. a cop
A cop + editor as known innocents would turn into "just do what us 2 decide or you are suspicious"
