In relation to shutdowns, I'm just curious, do people get their entire Amazon account shutdown or is it only for the AP portion?

I'm thinking about bringing my brother into the fold

Currently I'm A, doing A > B to B bank, would end up doing C > A > A bank, A > B > B bank, B writing me a check/cash and doing C > A with GC

However I know he is not willing to risk losing his Amazon account over it, as he is in love with Amazon, so just curious on what happens with people's accounts in reference to shutdowns.
