The book says that the only way "they" will know "they" are being Mind Blocked is if "they" Detect Psionics. Makes no mention of a third group of observers standing outside the area, just the "they" that said evil psychic is Mind Blocking. Hence it is good for preventing mind to mind contact, not acting as some sort of super damper.
Therefore see post above.
What the book says is:
"Thus, a villianous psychic can use the group mind block for his own evil purposes. Everyone within the 120' area of affect will be automatically blocked, but the effect is not detectable so they are not likely to know that they are being mind blocked (A detect psionics will indicate a group mind block)!"
It's poorly phrased, and could refer to somebody inside the GMB, or somebody from the outside.
Now look on p. 115
"The probe can not be used to pinpoint the exact location of psychic energy nor the level of power other than a vague sense of weak, medium, or powerful, but it will indicate whether an individual is psychic by directing the probe at a specific person (does not reveal the type or strength of the person's powers other than low, medium, high). It will also indicate whether a group ming block is in effect and if a person is psionically possessed."
In this case, the reference to detecting a GMB is in the context of probing a specific person.
Which indicates that the meaning is this:
If a psychic attempts to probe somebody who has a GMB on them, the probing psychic can detect the GMB.
With nothing to indicate that the probing psychic is inside the GMB.
It looks to me like the purposes of mentioning that GMBs are detectable is simply to clarify that an outside psychic can sense a group of people who have on up, not any indication that the power can be used by you when YOU have one up.
