I believe this is not a new problem, it always exists in this forum and there is no specific solution or penalty  
Unknowingly, I glanced over and saw information about this guy. Let's take a look at his merit: here
It includes 17 merit from one user, XinXan

Now let's take a look at the posts which received merit:

All posts inform the service. Are they worth for those merit  
About XinXan, his history does not give such merit to anyone, not an active user in merit.

So my question, what is their relationship? It seems that Merit is being abused without any punishment for such things   Any other comments, let me know what you think
