Can someone highlight how this forum earns money to pay for its services like paying for the hosting services etc.?
It's obvious they pay a lot of money to host this forum because it has many members and new content every single day! The good thing is that I see ads under topics, and if I start my own topic an ad will appear when the topic get at least one reply. Maybe they also get money from copper accounts because I see a lot of copper accounts in the bounty section.
Secondly this forum is created by satoshi but he is no more active. So who actually is the true administrator of this forum?
I only know Theymos as the head admin, but he appointed moderators to help him because it is a tough job to manage the whole BTT forum yourself. That's why you'll see different moderators manage some categories (subforums).
