THEMA: Earnings and fanrank

I started with this site, for the 5th time, after having already made 4 payments. I have 166 friends on facebook, 207 on instagram, and 406 on twitter, for a total of 780 between friends and followers! Although they are not small numbers, I have a fan rank of 3! The first few times I started with this site, I had far fewer friends, but a rank 4, and I was able to make at least 30 cents a day! From yesterday to midnight to now, I earned 8 cents! ! I would like to know why, a few days ago I started again and the instagram was paid 2.5 or 3.5 credits! Now they are paid 0.60! Follow 3 profiles for ....... 1 cent! There is something wrong with this site and a joke appears to keep on "earning" like this!
