A post about a HYIP (technically a ponzi scheme) is getting filled with payment proofs. Most of which come from newly generated accounts. This kind of replies are the most spamy replies one can make. They take no effort to create whatsoever, hundreds of people could post them every day, they involve advertising spam and hidden referral links.
