Wowzers, I wonder if it's TGTBT (Too Good to be True).

Another person back in March had a 411 on her: http://www.theeroticreview.com/discussion_boards/viewmsg.asp?MessageID=42889&boardID=19&page=

Her ad at least has been around--the original web suffix was ny-missd1-sonia1 before EROS went to numbers in July.

No reviews that I could find, which I feel is always an indicator for caution.

Plus, take a closer look at her ad:  "i love men age over 40 years and older dont call me if you are younger then that thanks i like experienced men they are my type"

Hmmmm, men over 40 and experienced.  I'm not so sure she would be very good for first timers.  And, it sounds like she's looking for a sugar daddy.
