It might be helpful to address the fact of why there are different spellings in the first place: in ancient Egyptian hieroglyphs there really isn't much vowel information provided by the glyphs, they are virtually all consonants. Hence most of the vowel sounds are added for us modern folks' convenience. In the shortened version, which are being labeled "kuk/kek", the actual hieroglyph is just two "k" sound glyphs together as in: "kk". In fact, you would probably see "Kik" too if it weren't for the fact that there is actually an "i" sound in the hieroglyphs (though it wasn't used as a vowel in their language -- they didn't write down their vowels). Nevertheless there are some ways to derive the vowel information from derivative languages -- for example, the Coptic language (Egyptian spoken language which is grammatically similar to the hieroglyphic late Egyptian language). In the Coptic language an "eh" sound, assuming there even was an "e" like vowel sound in the first place (a big if) would have normally defaulted to an "oooh" sound when pronounced, possibly making it pronounced "kook" in actuality (so there is good chance both "kek" and "kuk" are wrong. But basically, a lot of these things are just their best guess, and philologist/linguists would be the first to tell us to keep in mind this is a culture that spanned 30 centuries (!). I mean look at how much English has changed in 2 centuries... In summary, we modern folk probably don't know shi* about poop. This is especially true if one accepts what Ra told us about the Egyptians as true.
Though it seems apparent, to me, this "cult of kek" has always been satirical, and like all great satire there are always a few people who inadvertently end up taking it seriously. Just go read the comments section of an Onion article. There are lots of people who think those are real articles. Personally speaking, I find the notion of an actual kek cult somewhat ridiculous, but I also find the idea that it was the result of Russian "astroturfing" equally preposterous.
