Steam bans. How to separate accounts?

[Pip]

Hello,

 

I ran a BOT and it had 40 steam accounts connected to it. All of my 40 accounts were banned in the same time. How can Steam detect and link those accounts among each other?

 

I was using:

- Each account was registered via different IP.

- Each account had unique phone number, email, password, name, etc.

- Funds were added via Steam gift cards or paysafecard codes.

- Each account was logging to Steam via proxy. Each account had different IP.

- I was logging to accounts via web browser with VPN (different iP's), incognito mode, cleared cookies each time.

 

Even though those safety precautions all accounts were banned at once. How could accounts be linked? 

EMachineIDType - it should be probably set to "None". 

What else can I improve? 

 

Please give me some suggestions.

Violating Steam terms of service.
Sending and receiving a lot of one-sided offers.
