Single post in Referral Renewal

Now that I heard this,I really wished I didn’t come to PFQ just by finding it from Youtube,kinda wished I had more friends back when I joined in like March or February 2018 xD. Now i’m tempted in inviting all my friends on other sites so I CAN GET THAT LETS GO EEVEE I.NEED.IT I’m kinda confused on why the refferal system is a thing,i’m assuming its rewarding the user on inviting new users,as PFQ wants many different users?
