for starters we have Links to Avoid #13: ""Sites that are only indirectly related to the article's subject: the link should be directly related to the subject of the article. A general site that has information about a variety of subjects should usually not be linked to from an article on a more specific subject""
 Hepatitis C and Watersports (urine)
 Watersports for HIV+ people
These two links are about watersports AND ____, while the article is simply about Watersports. They are also clearly in violation ""Important points to remember #5"" - ""avoid separate links to multiple pages in the same website""
Then take a look at the rest of the links under the lens of Links to Avoid #11 ""Links to blogs and personal web pages, except those written by a recognized authority"" It is completely unclear who is responsible for any of the websites and so we cannot know if the author(s) are 'recognized authorities' or if these sites are purely original research. 
So, how do any of the above links qualify to be included as external link? 207.69.139.144  "
