I believe this site is using old ads and trying to get the subscriber to pay for them.  I scanned the link and about 60 of the 65 ads are ts providers in LA. Some have similar ads on eros and some have changed their names, looks, etc.  So, in summary, old info.

As for Alyssa and Ivy - search here.  Ivy has been discussed a million times and the info is at your fingertips.  I personally would pass on both. Ivy is a man hater and as sexy as Alyssa can be, is somewhat cold and not personable.  I hear after the third or fourth visit, she warms up. Well, that $1000 later.  No thanks.
