I have actually gotten ads on OWF before but that was purely the result of adware and letting someone else use my computer who promptly decided to download XSpeedBoosterTotallyHelpsV2.1 and OhGodDownloadMoreRAM 1.0023_69.
I've also had ads on the OWF thanks to Adware. Damn software sneaking in some more dodgy software I didn't want. Took the absolute piss to get rid of it.
But yeah I'm really glad the OWF doesn't have ads. Not to mention this is probably the fastest websites that loads other then Google.
Because OWF is hosted on an 'unlimited' host for like 5 bucks a month and that hardly worth putting ads up for. Also it's a fan site, it was never meant to make money.
