That's exactly what I was thinking.

Thank you very much for confirmation!

So someone has written program that quickly sends incoming BTC and is strictly connected to the network, right?
Correct.

This is a brain wallet. Brain wallets are inherently insecure, and this is an incredibly insecure one at that, given that this brain wallet is generated from an empty string. There are public databases out there which show tens of thousands insecure brain wallets, along with their associated generation string, which have been used in the past, and there are individuals out there with private databases with hundreds of thousands more potential brain wallets generated from things like words, common phrases, song lyrics, book/movie quotes. These individuals set up bots to monitor all these addresses, used and unused, and as soon as any coin is deposited immediately sweep it to their own wallet.

To me there are a few possible options on why this could happen:

-It is some kind of scam, where maybe people "generate" a wallet, but in reality the program gives an already known address where the scammer has the private key and quickly takes the fund via a script.

-An exchange, that takes the funds from the specific import address

-Some kind of payment provider

All of that is for sure not done by a human and could be done by a script if you know what you are doing.

I am observing empty string brainwallet (empty string converted to BTC private key = WIF). While ago someone has put on it 900 mBTC, which has disappeared quickly within minutes (or less, seconds).
Two days ago someone put ~21 mBTC on the same address. In the same block it has been taken by someone else. Once again only seconds.

Tell me if I am wrong:

1. this is not manual work when someone is sitting beside Bitcoin Core and manually making an outgoing transaction for incoming BTCs
2. this is not automatic work when Bitcoin Core is scripted for example in Python or Bash via API/CLI/RPC, that when there is coming anything it will be sent right away
3. this is automatic work along with outside-Bitcoin-Core communication, as the script/program is very fast and as the incoming transaction comes, it is right away sent in the same block?

So someone has written program that quickly sends incoming BTC and is strictly connected to the network, right?
