we should not have bad thoughts to others.
Sure we should. These people who abuse the merit system are cunts.
I think the key here is the quality of their posts. Maybe they really deserve 50 merit because of good post quality.
Posts look pretty bad, plus the format of the posts looks very similar. These accounts are probably alts sending merit to each other--which is basically what you'd expect them to do. This is probably enough evidence for actmyname to tag the account(s).
If you're looking for the Zen cow version of bitcointalk, try whatever local board fits that description. People who abuse sig campaigns, shitpost, give merit wrongly, sell/farm accounts, and commit every other bitcointalk offense are going to get called out for what they are. They richly deserve punishment.
