Regardless of whether they are friends from the local board, the way merits are distributed indicates that this is a lot of alt accounts or
"friends" communicate in the way
"I wrote a good post, please check and give merits". It is absolutely certain that it is not a coincidence, because when someone gets 10+ merits on the third page of the topic in the Speculation board for a post that is not special in any way, it is not something that should be considered ordinary.
What also attracts attention is the fact that the merits were given by one user in very short intervals, which clearly shows that the person giving the merits did not read those posts at all.

It looks like someone found a way to still rank up shitposters despite the Merit system. He's close to Sr. Member now. Maybe we should raise the Merit requirements for those ranks 
The merit system is not perfect, but without it shitposters and alt farms would have a much easier job. My opinion is that the merit system should be slightly adjusted, so let's say the maximum number of merits that someone can receive from an individual user should be reduced from 50 to say 30 (or less) in one month. This would not solve the problem, but it would slow down the progress of those trying to outwit the system.
