Ps plus collection sharing

My friend is gonna get a ps5 real soon, his brother and I have ps plus subscriptions on our accounts. I’m sure he’ll put his brother’s details first and that is completely fine. But if he puts my details as well, will that get me or him banned? I don’t want him to even risk getting banned the games can wait. But if he does the ps plus sharing for like 2 people would that be risky?
