Why are "encounters" allowed to show

The websites that aren't affiliated with Eccie, but Bio Pages aren't?

If I understand your question, the link that apears in an Encounter Report is entirely up to the gentleman's choice. He can list a website, the girl's advertising site or her Bio Page if she is an Upgraded Female Account. Many Encounter Reports contain Bio Page links.

It is a way to let that female show her other ads on other sites, so why can that female have this site show up but Bio pages are not allowed to do the same? There is no difference except someone else posting it and it's just favoritism

Your claim of favoritism is ridiculous. A decision by ownership has been made regarding what Bio Pages may contain and what those pages may not contain in the best interest of the site, not of any one person or to harm any one person or group of persons.

If you don't like the way this site is administered, you can always disable your account.
