Wouldn't iot be fun to make a pseudonym of "Tom". Teehee.
But, more seriously, pseudonyms will do very little. In a game where a not insignificant number of players regularly study each others' writing habits in an attempt to mimic and forge each others' letters, and where we all read each other quite regularly IG and on the forum, I do not think a pseudonym will be any protection of identity.
I think you vastly overestimate the number of people who can do this with any great degree of accuracy.
Not to mention the intersection of that set with the set of people who would care enough about any given Titan decision to make the effort.
And the intersection of
those sets with the set of people who have actually come into close enough IC contact with the Titans in question to have a viable sample.
And all that is leaving aside the question of how long it would take them to go through
all their correspondents who sound sort of similar to narrow it down.
