Well...that's a step in the right direction. Rather than pooh-poohing the need to take any action at all, now you suggest, that the rest of ME, and specifically the Elves of Lorien--may have taken action.
No, people had already said that investigations might have been made, this is nothing new. Aragil and I both suggested the possiblity a day or two ago. I specifically said that Gandalf and/or Aragorn, both of whom say they have entered Moria before, may have been investigating Durin's Bane, without success.
Unfortunately for your current argument, Occam's razor says that the absence of something implies its absence--not its presence.
Occam's Razor says no such thing. It says the simplest explanation is usually the best. It does not guarantee that it is correct, nor does it say anything about the absence of something proving its absence.
As for the dwarves, they had all the information they needed. Durin's Bane was Durin's Bane -- a nasty, terror that they could not defeat. You keep trying to apply real world logic to a magical world. Big, nasty creatures occurred in Middle-earth. I didn't see any reports in LOTR about investigators being dispatched to find out exactly what kind of creature the Watcher in the Water was. Why hasn't old Tom Bombadil done something about nasty Old Man Willow who seems to have a penchant for giving Tom's Old Forest a bad reputation? Why haven't Gandalf and Aragorn done something about those Barrow-wights haunting Aragorn's ancestoral burial mounds? Why hasn't Legolas' dad used a big can of insecticide on those spiders in Mirkwood? Why didn't Elrond and sons clear the orcs out of the Misty Mountains after the orcs did unspeakable things to Elrond's wife? What about good old Shelob? Why didn't the kings of Rohan hire an exorcist to clear out the Paths of the Dead and give them a short-cut to the sea? A lot of Middle-earth was a scary place.
