This is the lowest Chester's can go in my opinion because $5 is a kind of too low to get the attention pf any reputable forum members and only newbies and Jr. Members will take such offers seriously amd if you notice a trend in the suspected accounts you will see that their are alts and most are low ranks.
Hope we get more evidence that we can nail the down, I have always viewed those low paying reviews campaign ranging around $5 to be a spam fist ground for alts farmers and bounty cheaters.
