How can mylot earn money?

Tweet

I ask myself, how can mylot earn mylot for the users and admins just by users making discussions. Like I know the way of the paid-to-click websites but in here there isn't much publicity or surveys or pop-ups. So I don't get it. Like the only publicity i see is when i login and when i choose the type of discussion where those movies and games appear. Thanks for reading and sorry for bad english in some sentences
