It is expected that escorts will use professional names. Some girls use different names on different ad sites, thou I'm not sure why.
Which ever name you want to use try to at least stick to one name per ad.

Recently when browsing on one of the ad sites, I came a cross an ad page for a girl that had one name in the subject, another in the description area, and a third next to the phone number.

I hope the girls didn't have some kind of disorder.

Ladies always a good idea to proof read your ad. Also, maybe it would be easier to stick with one name to use professionally.
