I personally don't have the time to live on Bitcointalk.org. I work 50+ hours a week and login to bitcointalk.org about twice a day to sale misc goods. Now is this fair to me, or others like me, that we can't rank up because of this? Again, opinions are like assholes, everyone has one. And I'm fairly sure you know mine. Point is, if Theymos can sell whitelist to be able to post more on Bitcointalk, then selling Merit Rank-ups should be no different.
If you only use the forum to sell stuff - why do you care about merit and rank?
Thats really simple and a dump question both. Who will get more sales? Legendary vs Member
