Dishonorable personalities and honor gain (L5R rules board)

A topic from AEG's L5R CCG Rules forum, copied for Oracle of the Void from a copy of the forum saved in October 2015, so pages it didn't save are missing. Players' names are left out; the rules officials are named. Rulings are as they stood on these dates; later rulings, the rulebooks and the Rules Archive may differ.

A player, 24 July 2014

I just started playing the game again and my play group and I had a disagreement on dishonored personalities and them being involved in gaining honor. They say it's a choice to gain the honor instead of rehonoring a personality via the rulebook and what was shown in some Ivory edition video by the designer on Youtube, a video I couldn't find.

I myself disagreed with this as page 23 of the comprehensive rules clearly state

There are a number of ways to rehonor dishonorable Personalities. Before a player gains one or more points of Honor from an action or trait that targeted or came from one or more of his or her dishonorable Personalities. If rehonoring the Personalities is not one of that action or trait’s effects, the dishonorable Personalities' rehonoring is substituted (p. 59) for the Honor gain. Before a player gains Honor from attaching a card to one of his or her dishonorable Personalities, the Personality's rehonoring is substituted for the Honor gain. Before a player with one or more dishonorable Personalities in his or her army gains Honor from destroying enemy cards in battle resolution, all such dishonorable Personalities are rehonored, substituting for the Honor gain. In a tied battle, all dishonorable Personalities in anarmy are rehonored before being destroyed, in substitution for their army's leader's Honor gain.

It was always played like that from Imperial to Gold edition. As for any changes after that I don't know if there were. Am I correct or have they been playing it wrong?

Also why I'm here, another question. Is there a limit to the amount of times in a turn you can use the Imperial Favor now?

If an effect would rehonor a dishonored Personality, you must do so. You do not get to choose between honor gain and rehonoring.

For your second question, you may discard the Imperial Favor as many times as you need to to fulfill effects on cards or the two Favor Rulebook Player Abilities, but those Favor Rulebook Player Abilities are still limited to Once per Turn by default.
