Suspends often occur because of the problem of changing IP addresses.

hello, I want to ask about a suspended account, my account is often suspended by github with the reason that I often change ip addresses, but I use a mobile network which causes my ip address to change frequently, I have tried to contact the github support team but they responded with same answer, I don’t understand anymore why github suspends accounts that frequently change ip addresses, I’ve been suspended by github for 5 accounts with the reason that my ip addresses change frequently, please provide a solution.
