Please do not add commercial links or links to your own private websites to Wikipedia, as you did in Anal leakage. Wikipedia is not a vehicle for advertising or a mere collection of external links. You are, however, encouraged to add content instead of links as long as the content abides by our policies and guidelines.  See the welcome page if you would like to learn more about contributing to our encyclopedia. Thanks.   A link to the edit I have reverted can be found here: link. If you believe this edit should not have been reverted, please contact me.
