Looking at the other recent posts.
It just seems like they're mad that Rev is living the trad lifestyle (he's married, he has a house, he has a fancy car, he has pecs and six pack abs). So this seems less like Kiwi Farms bashing on Rev for being a lolicon and they seem more jealous that Rev gets to live the trad lifestyle that they can only dream of.
To me it seems Kiwi Farms is envious of Rev. In other news, the ocean is made of water.
Much like how Youtubers killed traditional video game journalism, Youtubers and streamers killed the forum (this includes Kiwi Farms).
One meme I remember that was prevalent back in the day was "Too long; didn't read" which was a rude but blunt way of saying that if you are going to drop some knowledge about anything then follow the KISS principle (Keep It Simple, Stupid). Don't bombard your audience with information that they may not even care about, just stick to the relevant details.
Youtubers and streamers do a better job to cover lolcows better than Kiwi Farms because most people are not willing to read a novel about a lolcow when they can always watch a short video that's short, sweet, and gets to the point.
Keep It Simple Stupid and follow the principle of showing rather telling or else you will bore your audience.
This is also why I rarely even pay attention to video essays because they're often too bloated and a lot can be cut down to get to the point while still delivering the same message.
