Page Deletion Request: YouTube Mirror
YasakTube was not a video-upload site, it was one of many "tunnel" websites which sprang up during the access-block in Turkey, which lasted from 2008 to 2010.
This is further indicated by a near-identical UI, and a disclaimer at the bottom of their website openly stating that the contents were being mirrored from the actual YouTube.
Although nothing of value was lost from its shutdown, WayBackMachine screenshots from days before the access-block was lifted show traces of the trends from the time, which perhaps wouldn't have been documented or archived in any other way.
It might still deserve a page somewhere, but I'm sure that marking it as lost/saved isn't really applicable.
