This is true. This website is a part-time project, and cyberspace is never free. Advertisements help to cover some of those costs. If you click those ads, you're actually probably indirectly doing Hullbreach a favor.
If you see an ad that interests you, then please support the advertiser - which, in turn, helps to pay for hosting of these websites. But do not repeatedly click the ads, because advertisers will detect this fraudulent activity and may cancel the account without warning. Google is the worst with this. They have shut down two AdSense accounts I've had for what I can guess was someone rapidly clicking ads. Since they won't tell me, I suppose I'll never know. All I know is they pocketed $490 of my money.
