If you look at the breakdown of the link, you'll find a lot of information.

After the /files/ part, you'll see lv-gabriella20.  That's the owner of the account with Eros.  The lv part means that it's a Las Vegas account.  When you see ad after ad with that account, you'll come to the (correct) assumption that it's an agency, in spite of the fact that her ad probably says that she's independent.  If she's lied about being independent, don't you think that she could lie about the picture being her???

Now, if you've done your homework, you'll know that with almost no exceptions, agencies in Las Vegas are a very bad thing.  So, to answer your question, the vast majority of ads on eros-lv are for women you don't want to (or won't) meet.

When the account owner, and the ladies name are the same, you should then look at TER reviews.  That will save you a lot of time looking here for reviews that don't exist.  Most of those agency girls have no reviews.  Once one pops up (almost always a 1), the name goes away and a new one pops up.
