I’m shocked, shocked that a content filtering product is working in such a manner!!
No, wait, I’m not, actually. TBH, I was rather expecting this; content filters are very difficult to get right and require nearly constant maintenance to not lag too far behind the weird, weird web.
(My creds: I am (sadly) the admin for the nanny filter at the company I work for, which is ironic because I’m against content filtering on almost a religious level. However, it also acts as a security appliance, and keeps our employees on task instead of looking at failbook all day long.)
