I think that most of the expenses are paid through the ads, but I'm not sure if they have other business ventures that they can money from. Also, I've noticed that they do have a fair amount of ads now, even in the middle of forum topics. That could probably account for the bills. The rest they probably pay from their own pockets.
There is four sets of ads on each topic page. so they are probley getting the money from that.
of course it is possible~~
i have seen a forum recieves more than $1000000 a month !!!
The ads are pay-per-click, so Bondings gets money whenever someone clicks on the ads.
But I do believe that Bondings pays a bit out of his pocket... You'd need to wait for him to reply.
FriHost's servers cost few hundred dollars per month.
If i'm not wrong, 99% of the price is payed by the ads.
Anyway, the question has been answered by several users.
