The rule is in place to ensure that those who wish to view Zelaron from work or a formal environment (such as my office) can do so without risk. According to your logic, if I had full blown hardcore porn up as my screensaver in the office that would be alright as long as it was blurry and covered in censor bars. It doesn't work that way. The presumed intent is more of the issue. If WW's boss walked in and saw a huge image of a woman naked but covering herself with her hands, you can bet that he wouldn't say to WW "well, as long as I don't see any nipple it's O.K."

If you can't follow the rules to respect the rest of us, don't expect to garner any respect.
