there is good possibility that many among this list (may be 50%) are just random by luck. I guess this list can be ignored if they are distributing mertis among each other its ok. I don't think they can abuse that much. Of course they will run out of sMerit very soon.
As
theymos said in one of his quote its not of much an issue:
Merit sales, transfers to aliases, back-and-forth trading, etc. are not much of an issue. All illegitimate merit will decay, and will account for a tiny and very expensive fraction of the total merit economy.
We are in good hands so merit trades should not bother us much

then the small volume of black-market merit trades don't themselves bother me much, and I think that it does more harm than good to get too witch-hunty about it.
