That is the reason,the Youtube autoflagging bot follows the 301 and 302 redirects in your links in the video description just like facebook bots to find links believed to be spam.Youtube sees Clickbank links as spam therefore flagging your video as inappropriate.A way around this is to buy a domain and use a meta refresh redirect ,so that it will redirect to your affiliate link.I find this out when I uploaded a video without a description for a "make money online" keyword and made it public ,it did not get flagged for 24 hours,but as I put my affiliate link in the description it got flagged by youtube within two hours as inappropriate.

I did not buy any views or used the unlisted method on this video.
I think meta-refresh is still a redirection and it will still follow
