On visiting many PSP sites i keep noticing some ads that really do harm to the Homebrew Scene and worst of all most sites will struggle to do anything against them, the ads in question are those ones that offer PSP Download Services or Guides to Downgrading or even an App that has Emulators with Roms in.
It seems that Google being the almighty power it is cant control the advertisers that use its service, the amount of Rom ads and especially those PSP Download Services ads (although some lesser sites actually have those ads direct and not via Google.) do major harm to the PSP Scene, if they are allowing downloading of ISOs and Movies etc then they deserve to be shut down. If they are enticing you to pay for homebrew then you are being ripped off majorly. Any site that openly supports these paying serviices might as well be a warez site.
