This is a unique case so I took some time to look into it.
It would appear that the "merit abuse" part has to do with these 4 accounts:
steve_rogers (banned)
timoshani nastyabor (banned)
dimplit (banned)
sending a total of 10 merit to this account:
AsrRustam (banned)
Here is what the sent merit network looks like:

I know merits are for the most part subjective, so you will need explicit comment from theymos or else whoever did the banning in order to know more.
Okay, finally smth that could be very hardly called merit abusing, but still it's noting. Nevertheless thanks for your job.
