First of all, disable comments and ratings on the video.
And also DONT PUT ANYTHING IN THE NAME SECTION
Go on img.4chan.org/b/
At the top you will the a post maker, there copy paste the youtube link in (in the big space) with YOUTUBE PORN /B/!! COME GET SUM LAWL!! ( or something like that)
For the file, select this image: http://nerdiest-kids.com/wp-content/...0/pedobear.png (You must first save it)
Then click "submit", and find your thread. Hit the "reply" button, at the top you'll see the same layout. Now keep on replying, hitting the back key, replying, hitting the back key, (not to fast as there is a flood detector) and bump it with stuff like "MOAR" and "OMFG CP ON YOUTUBE YOU CRAZY SON" etc. etc. ( BE CREATIVE!!!)
Keep on bumping the thread like 20 times, and then abandon it, and redo the thing over again.
Hope this helped, tell me if something fucked up,
