I'm sure everybody has a valid reason.
My handle was selected because I wanted to be able to post on the board with the same anonanimity that the gentlemen have. I wasn't planning to use Perb as an advertising venue.
After somebody outed my handle as being me, I figured I may as well become a paid advertiser and put in my link.
I'm sure that is a fairly common reason for many of the ladies on here.
Another common reason may be that there are only so many names, and a number of
Vancouver escorts share the same or very similar names. A ladies preferred name may already be taken (even if it is by somebody who never posts) or it could be very similar to another handle, and in an effort to reduce confusion, selecting a completely different handle seems to be the appropriate action.
