Q:

What is a KMorG Word™?

In the spirit of the What is a Word™/Phrase™ series started by JLee, a special brand of Phrase™ and Word™ puzzles.

(ApoloGies in advance, I seeM to be havinG soMe trouble with My Keyboard today.)
If a word conforMs to a special rule, I call it a KMorG Word™.
Use the followinG exaMples below to find the rule.

The puzzle satisfies the series' inbuilt assuMption, that each word can be tested for whether it is a KMorG Word™ without relyinG on the other words.
These are not the only exaMples of KMorG Words™; Many More exist.

—HINTS— 
helpfulness level 0: 

 There are no fish, red or otherwise, in this puzzle.

helpfulness level 1: 

 The What is a ... Word™ boilerplate and flavor text is not part of the actual puzzle; spastic capitalization therein does serve a (faintly fishy?) purpose, but can be safely set aside.
 In the puzzle proper, case is intentional and relevant.

helpfulness level 2: 

 With apoloGies to Ferdinand de Saussure and his MaxiM:
TiMe chanGes all thinGs; there is no reason why these lists should escape this universal law

helpfulness level 3: 

 Why are only certain letters always capitalized? What connotations could those letters share?

helpfulness level 4: 

 Were I to add no-computers here, this puzzle would quite certainly be unsolvable.

helpfulness level 5: 

 What is the value of a KMorG Word™?

helpfulness level 6: 

 Today I was on a 10K run, but stopped for a while to see an open house for a property that's been for sale for $950G since MMIX. It was a nice place to visit but I wouldn't want to live there.

helpfulness level 7: 

 About helpfulness level 4's hint: the (only) reason no-computers is not specified is because, while a lot of words can be ruled out as KMorG Words™ by inspection, nearly all the words listed herein require both awareness of what to do, and a web browser (or equivalent, such as "curl"), to ascertain KMorG Word™ness... but no deep technical arcana or capability should be needed.

A:

I think a word is a KMorG word if and only if

 it corresponds to an image on imgur.

Reason for the name:

 "A picture is worth a thousand words".

So, for instance, the first few KMorG words are

 bands, basil, and bawdy

and the first few non-KMorG words are (or, perhaps better, would be)

 GanGs, thyMe, and ribald.

Some comments on the hints:
Level 1 "In the puzzle proper, case is intentional and relevant.":

 Indeed it is, but the fact that K,M,G are capitalized and other letters aren't is (despite the level-0 hint) pretty much a red herring. (Though perhaps @Rubio would claim that the correct criterion is "capitalization follows the convention found in the puzzle, and the result is an imgur image".)

Level 2 "Time changes all things":

 Some things that are not presently KMorG words might become such words later as more images are uploaded to imgur.

Level 5 "What is the value ...":

 A reference to the "A picture is worth ..." saying.

Level 6 "10K, $950G, MMIX":

 Just steering us away from the idea that M=10^6 and G=10^9.
