preeeetty sure that's bannable.take it down.
But with 62 quintillion possible video IDs, you'd be waiting a long time for a working link.
http://anyspieceofinter.net/randid.phpopen them all, if you start hearing random voices you have a hit :)
Okay. Opened all 100 links, none were existant videos.
youtube api has youtube.videos.list that you can use to request videos by id and have it return the ids of the ones that actually exist
How would that help though?
