One Doubt :

In special events,ie like
shout quizes,to gain points...saying
'inbox' me correct answer...who answer
first will gain points! BUT HOW TO KNOW
THE HOST IS PROVIDING POINTS TO THE FIRST PERSON ITSELF? We cant see his/her inbox! Can someone Explain the details behind this?... Or do we have to buy what quiz host always say?

please Note : It's a doubt of mine as a newbie, your ideas/views are welcome here. Thank you so much
