The older versions of IE back in the Windows 9X era would essentially turn into Windows Explorer if you put a local file path into them. I remember using this exploit back in the day on our school computers that ran a locked down version of Windows where you couldn't browse anything in Windows Explorer beyond your personal network folder. I found that by typing C:/ into the IE address bar it would turn IE into Windows Explorer mode and from there I had full access to the C drive and could even open up the folder tree sidebar thing and browse the local network, finding all sorts of folders that I wasn't supposed to be able to access.

I feel like they will ban it anyways before their IPO along with any other communities they deem "controversial"
