How about a slight alternative...

Your character gets one comment about any/ever other character, with some short limit... one-liner. You may update it as many times as possible. You may read your own notes.. and an imm may read all notes associated with that character.

You could add a note like this:
charnote lornis badass shifter gator/croc/ice-drake great roleplayer

Read your own note like this:
charnote Lornis
badass shifter gator/croc/ice-drake great roleplayer

Imms could run a query for all of a char's charnotes.. or allver. charnotes for characters 40+.

It has the added benefit of letting players keep track of cabal/killed me/ranked with me without having to keep notes on paper or whatever

Of course.. you could leave out the whole player being about to read their own note... which would improve the helpful comment to useless (from an imm standpoint) ratio.
