As a bit of a disclaimer, I know pulse who is in my clan has been posting in his defence, but I've got no relationship with ghost or motivation to defend or accuse him one way or the other.
In that replay I can't find anything overtly suspect, or once more enough to make me suspect a map hack. A slightly suspicious moment was his selecting his units before the attack came in, but other than that there wasn't anything I could pick up without explanation. Some points in his favour - Scouting probe was sent, and not only that but his player cam actually focused on the probe to examine his base, meaning he is trying to scout. Later on there was an engagement after trying to place a pylon at the watch tower but unfortunately it was caught out of position and killed by the army.
Sorry that I haven't watched your vod nemo, and you may have raised more issues, but I suppose on the flip side of things if it isn't obvious for a first watch / examination perhaps we're looking for things a bit too hard.
Again, inconclusive enough to give him the benefit of the doubt.
P.s. If it is a hack, i don't think it's a map hack, I think it's a minimap hack. Any suspect things raised so far could be shown by being able to see his units on the minimap, with broad general unit movements apparent. It doesn't seem as though he is actually looking through the map however because his camera movements are always located within his base, not looking over fog of war, etc.
