Krydos would be the one to answer this, so I'll move it and let him explain the details, but most of that money goes to Hurricane Electric though ($400 IIRC) with the rest going towards software licenses, domains, etc. For what it's worth, we haven't had a month in the black since last year. We have money in the bank to operate for a while yet (2 years or so), but we're far from sustainable and if this trend continues, we will eventually end up going bankrupt. Google Adsense used to be our primary funding source, but they no longer allow us to use their ads on our main pages (our website, suspended pages, etc.), erroneously claiming there's "no content"...and of course being Google, there's absolutely zero customer support to speak to about that.
