Steam

By what parameters is a red sign given in Steam (IP, hardware)?

Answer 1

The main parameter is the desire to violate the rules of Steam.
And also, in fact, non-compliance with these rules .
Further algorithms + manual check work. The details of the verification and operation of the algorithms are not disclosed , so that any hackers and cheaters have less opportunity to bypass protection.
In general, this approach by Valve is reasonable. After all, if you reveal all the details of protective measures, then it will be easier for cheaters to look for holes in the protection in order to bypass it. It is easier for a company to eliminate one pest than to listen and process complaints from all those it harms.
In case the red plate was obtained by accident, it itself contains a brief information about why this could happen and what to do. Then you just need to remember your / others' actions on the account, and guess the reason. In theory, you can try to appeal the punishment. But if the rules were actually violated, even purely by accident, Valve is not obliged to satisfy the complaint. Ignorance of the rules or negligence in their observance does not exempt from liability. The company is well aware that hackers and cheaters will try to hang noodles on their ears and put pressure on the support, too, so any words of the user are, by default, zero trust.
