I concur on the fact that the 2 merits awarded today are completely undeserved, and therefore have a suspicious appeal, besides setting a bad example for others on the Beginners & Help board. Those merits will remain suspicious in my opinion, due to the content of the merited post, but likely no one will look further into the nature of the sender’s account on the day to day run (I saw the sender’s selling post you must have seen, but only after you mentioned it and I did some digging, meaning it is not easy to see first off). 

Looking through the OPs posting history, you can tell that posts are not merit postulants, and that the OP even in the business of purchasing Facebook accounts, so not a great precedent to lift suspicion on this case...
