see this for an ex. https://www.youtube.com/watch? v=CuDHX8D8Fns&lc=z12dejb5ite0u5apz04cfnhx2rrrx3jrrqc0k ----- delete the space on the link he actually searches for the top comment and replies with his account and now NO ONE can reply to that comment anymore (try to reply to that comment) -- which means he will stay at the top for a good while and get some HUGE amount of clicks. If I post there a comment my link will disappear after a minute or so. Any idea how he does that?
