Staking TWvalidator on BEP8 mini token

Hello, I would like to understand how is possible that today on a BEP8 mini token that I can finally see in my TrustWallet, for this mini token, I read that I can STAKE it with TWvalidator. Because it is a token of a friend, I would like to understand how is possible this, the APR is 17%, who is going to pay this % if my friend stake his own token, and why TWvalidator would be interested to do so, for which scope?
