Honestly, it's not even safe to just type in the character names anymore. Just to search for a flippin' screenshot has its risks! There should be some way of sites that contain very graphic sexual images bein' labeled in order to warn Internet users. However, there is not enough control to enforce this. Unfortunately, my mind has been scarred by just typing in a character name or multiple character names and unsuspectingly comin' across one of those sites

My point is, one can never be careful enough with the Internet. If you've got a sensitive stomach, keep a wastebasket nearby

I tend to use Web of Trust, an add-on for both Firefox and Internet Explorer. It allows users to rate sites themselves (there's thousands of users) and each site has a few categories, one of them being Child Safety (this includes anything that is sexually graphic). When activated, when you do a search, each site will be labeled dark green (very safe), green (safe), yellow (enter with caution), orange (dangerous), and red (very dangerous). If you accidentally or purposely click on a site that is labeled dangerous, WOT will stop you from going to the site and display a warning.
To avoid sexually graphic pictures using Google Search, simply turn the safe search on. Also, though I never use it, there is a parental control program, free, called K9 Web Protection, which can block sites using keywords and force safe search.
