What advantage do you give to party members that know Fog of Jeer is an illusion or know that it is being cast (say a code phrase used by the caster like "Laugh it up")? Do they get an automatic Sensing test before it takes effect or do they have to go Aggressive and be hampered until their next action? +5 on it because the caster is telling them it is an illusion?
Every new Illusion or Figment is a new instance, and each instance has to be Sensed or Disbelieved uniquely. Just because the last frothing-at-the-mouth hellhound was an illusion does not guarantee that the next one is. Remember that every single spell FEELS REAL until Sensed/Disbelieved; if one goes around assuming that every door could be fake because one was, then you're going to have a hard time.
Sensing is a reaction to the subtle imperfections in an Illusion, but it takes either examination or interaction. Sensing is always required, even if someone else has passed and is attempting to convince others (during which time they grant a +5 bonus to those listening). So, you can't tell your buddies a secret phrase and give them a pass - that Illusion is still very much real to them until THEY sense it. As for having a secret phrase, I'd put that squarely in the column of meta-gaming - the spell would have a extra thread option of "Remove targets (X / Rank)" if that were an intention, otherwise I'd say that idea is basically baked into the system (I find it hard to believe that eighty million Illusionists before now have not had this same idea).

In that same vein, if a person with a very high Mystic Defense, one that would have prevented the Fog from being cast in the first place, walks into the area, are they affected? On one hand I can see the idea that you are casting an area spell in an area and the targets with Mystic Defense are part of that area at the time and once it is established it's effects have warped that area. On the other hand it seems a little hinky that you could cast the Fog next to someone that would normally be immune to it, then boot them into the Fog and they are vulnerable.
In this case, the Spellcasting test is a test to manifest the ability. Once it's manifest, anyone entering is affected. Seems reasonable to me - someone that was outside the original area has to knowingly walk into this creepy fog thing before it can take affect. If that doesn't scream "something is up," that person has other problems.

I get the, push them out of somewhere they want to be idea, that makes sense. How does casting a Fog of Jeer over a choke point make it 'hurt' though? You run through. And that's it. According to the spell description the Harried and Aggressive status only apply to actions taken inside the Fog. I suppose if you had someone holding their action that was able to attack at range they would be hitting someone with -2 for being Harried, but that's pretty chancy. In most scenarios someone runs though it, maybe says to themselves, "that was weird" and then does whatever they were going to do on the other side in the first place with no penalties to their action, right?
Fog of Jeer isn't a great example of barrier-type spells. Other spells, especially Elementalist spells, are better examples. However, it doesn't invalidate the point: given a choke point, like a corridor, you can have your close combat specialist stand outside the fog on your end, forcing enemies to enter the fog and stay within the area while confronting your companion, who is outside of it. That may SEEM a bit wonky, but it's fairly reasonable - the spell has a completely obvious area of effect given the fog, so it's easy for your companion to stand outside of it, but it's ALSO completely obvious to your enemy that it's likely in their best entrance to take a swing or two from your companion while they attempt to move beside or past them to get out of the obvious fog area.
