How hard would it be for someone who was so inclined (and wanted to frame someone) to use a bot to make it look as though that person has deliberately viewed child porn?
| Also, did you deliberately download a picture called zzzzz123.gif? Better check your cache! |
It really wouldn't matter if it had been downloaded, since I have a script that clears my cache and wipes all unused disk space every day. If the file was in my cache and wasn't opened, no link files or other traces should exist, and even if they did, the file itself would not exist on my computer, so there would be no issue.
To answer your original question, it would be possible, but would require someone to know where all of the traces are supposed to reside for a particular user profile, etc. It is not easy, and would require a lot of knowledge about the victim in order to make it stick.
