Thanks for your email.
The reason why you do not appear on the "Most Subscribed" list is because you have uploaded several videos which have been flagged by other users and our staff reviewed and determined were racy. Racy videos will ask users to confirm that they are over 18 and willing to view a video that contains adult content.
Videos that have been marked as racy will prevent you from appearing on the "Most Subscribed" list.
Hope this helps,
The YouTube Team
