How to Yroo

Is this site 100%? if so is it even worth putting effort into ?
I've got friends who have claimed to make 600 pounds which is quite believable as he owns a facebook group with 10k members, he keeps posting his ref link.

If this site is 100% and its worth it then is there any method to make quite money because i've searched a bit and found out that you can refer "yourself". Could someone elaborate on that?

Thank you,

A lot of clueless noobs with brand new BHW accounts have been promoting it recently, so that says to me it is probably shit.

It's just a cashback site with affiliates.
