As I suspected, they are indeed engaging in copy/translate/paste posting.
Let's start with this one:
kxwhalexkThis post is more-or-less a copied translation of
this article. The original is in Chinese. But when you translate the page using Google, its almost word-for-word the exact same.
Translated using Google, from the article:
The asymmetric encryption algorithm contains both a public key (Public Key) and a private key (Secret Key). The data encrypted with the private key can only be decrypted with the public key, and the data encrypted with the public key can only be decrypted with the private key.
From the post:
The asymmetric encryption algorithm contains both a public key (Public Key) and a private key (Secret Key).
Data encrypted with the private key can only be decrypted with the public key, and data encrypted with the public key can only be decrypted with the private key.
From the article:
Bitcoin uses an asymmetric encryption algorithm to ensure the security of every transaction. Every account (address) in the network is a public key in a pair of secret keys. The owner of the account will hold the private key.

From the article:
It should be noted that it is extremely dangerous to use a website to generate a Bitcoin address and private key . We do not know whether the website will store a private key, so it is recommended to use a Bitcoin client to generate a public-private key pair.

Here is the clencher -- he used the same BTC address as the article as an example:
Among all 35hK24tcLEWcgNA4JxpvbkNkoAcDGqQPsPBitcoin addresses, there are currently more than 250,000 Bitcoin held in the addresses, and the current market value is about 2 billion US dollars.
From the post:
For example, we want to hack an account：35hK24tcLEWcgNA4JxpvbkNkoAcDGqQPsP（12/7/2021 101451.70580859 BTC），
We have to try 1.1579209e+77 times to crack his private key.
And yes, the rest of the post is also plagiarized, except for where he couldn't translate the word Summit and used the actual name of the supercomputer mentioned, which is Fugaku, which is another name for Mt. Fuji in Japanese.
So if you look at RainbowKun and some of the other overly enthusiastic/wordy posters in your list, I'm sure you can find similar examples. It's not quite as easy as finding same language plagiarists but still quite doable.
