This is continuation of the post I posted earlier.
It's surprising that the user (user2671112) who is member for 1 hour automatically get 100 reputations and donates that as bounty to another user (user2651613). It turns out that all of the answers by the former are accepted by the later and hence 100 reputations. A worst part is here and here where the user2671112 copies the answer of @agstudy and @Hong Ooi and then that are accepted by OP (user2651613). Notice that there is also another answer by the another user user2640560, which happens to repeat the process of user2671112. I reported in the earlier post here about the user2640560. This user is also re-posting the answer here for the question by the user2626657, that was suspended earlier.
