I know people who are very willing to work for 500 bucks a month, and that comes down to 6k per year. Do you really think that freebitcoin can't hire someone for 500 bucks a month just to list these things as soon as they can be listed, like literally the second they are known that person will list it. Of course there are times when they are asleep or when they are taking a break or whatever but in the end we are talking about less than 12 hours to list everything as soon as they are known.
They are currently paying 75$ per week their signature promoters, so yes I think they could easily save 500 or even 1000$ per month to pay someone for this task. It's really sad they won't be able to list a game of the NBA final which is one of the most wagered event in the world.
