If it says people have more than one name?

I think it boils down to IP address. A young lady I know has recently decided to have a rest and switched her profile from offering to seeking services. As I still have an email from her it now shows her to have over 250 aliases, some as WG's and others as clients. (this does fluctuate on a daily basis too) but if you look into some of the feedback it looks like they have all logged on through the same hotels wifi at some time.
