Never seen a rule allowing merit sales. Did I miss anything? Got the situation with account sales though, allowed but frowned upon.
From theymos:
The current status quo seems OK. If you have to pay $20 per merit plus a risk of getting red trust, then that's a situation that doesn't concern me at all. I'm not going to lose sleep over people going to ridiculous lengths to buy merit, since only a small number of people will be willing and able to do that.
As long as merit sales are a black market, I'm happy, since that makes it far more difficult and expensive to buy merit. If that's the case, 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.
I agree with him because it takes time to hunt them and tag them accordingly, as I said above, they'll get tagged by some DTs eventually.
