Is there a way to purchase merit to give away like Reddit gold?
There seems to be a black market for it, but you are not allowed to trade merit in any unethical manner. Merit trading, by whatever means, can get your account at least with a bag of negative trust, and likely on the road to being permanently banned if/when caught.
Its best if you dont even consider the option and play by the book. Posting such a question with your account immediately puts you on other people's suspect list.
