I’ve added a mandatory “Safe Search” filter to all images served up by ObSrv.
To most users, you won’t notice any difference, but the problem was that some people were using ObSrv to generate adult images, which got me in trouble with Google Adsense.
This is a business decision, not a moral one. Using ObSrv to generate adult images would get my Adsense account cancelled. No Adsense income = No ObSrv. Everyone would lose. So the simplest solution I could find was to block anything that didn’t pass the Google “Strict Safe Search” test.
If you find your image feeds aren’t generating images any more, please consider using less adult-related search terms.
