Agency alert:
remember
girls2please
newescortgirls.com
usa-escorts.net
escort-provider.com
bestescort4u.com ?
well here are some new sites which come from the same freak:
http://(provider's name).hotlocalescorts.org
http://(provider's name).escortqueen.com/
http://www.speedsurf.to/(provider's name).com
http:// (provider's name).andrad.com/
basically the best way to notice if an agency or provider is fake is that they all have the same link at the bottom of their page which says: my best friends with the same girls on all the sites. take a look at the attached link.
So what would be the point of a fake agency? Sting?/Rip off up front?
Some of your examples looked "too good to be true".
It appears that this guy is just trying to mess with people. He was banned from TER awhile ago. On some level, this may be his way of getting back at TER. Who knows?

As a general rule in the hobby, if something looks too good to be true it probably is.

The site I went to wanted to charge me about 30 bucks a month the get contact info on these "verified" escorts.
I almost got suckered into one of those sites. Luckily I was going to be traveling soon and wanted to see what was in other locations. The search showed the same results.
