As far as using Deodorize to lose that slept Goblin*... my understanding is that most mobs AGGRO to either sight or sound. Some aggro only to magic (elementals), some aggro to low HP's as well as sound (undead), and I'm somewhat sure there are sound/magic aggro mobs as well.
Separate from all of the above is whether or not the monster can TRACK by scent. Like most people, it seems, I don't have any first-hand experience about the subject. My educated guess is that if a monster does NOT track by scent, it will have no problems hunting you down (**goblins aggro to sight, and do not track by scent**), whereas you have a pretty good chance of losing a scent-tracking monster, via Deodorize or crossing water.

Poking aggro: IMO the Sea Horror aggroed the unfortunate poster by sound, like normal, and an ill-timed poke made it appear to have caused the attack.
This might stem from EQ or other games. Many years ago, in EQ1, I happened upon a wood that was formerly inhabited by halflings. During the recent Halloween event, nasty undead overtook the wood. I "hailed" a friendlier-looking skeleton from afar and was immediately aggroed and violated.
In Vana'diel, where you can roam 95% of the world safely as a 25 WHM or RDM (read: with sneak and invis), I have poked and comforted about every nasty I've come across, and no one was the wiser. ^^
