How to Tell FAKE ESCORT ADS and Fake Escorts: REAL Escorts do IT better than web-scammers
You can easily tell the real from the fake when it comes to escorts as well as escort ads. I am a real-life escort in Washington DC & Northern Virginia, and hackers have hijacked my real ads and phone number to misguide people. These fakers and ad hijackers want your MONEY. Don't give these scammers the time of day. Scammers work best when masquerading and copying what actual providers do. Escorts who misrepresent what they look like and what their services entail are also a stain on the industry. But first you need to know how to tell the difference.
Genuine escorts want to be found by genuine clients and set themselves apart online in lots of ways if you just know what to look for:
Real escort ads are up-to-date with specific details, especially details of how you should approach them for a date
Genuine escorts have more than one or two clear photos, or a link to another ad or website with multiple clear photos and up-to-date information
Professional providers operate locally and if touring advertise specific dates
Independant high-end escorts avoid sexual conversations before meeting genuine clients
Red flags for fake escorts and scam ads typically include:

Blurry photos like the one you see here to the right from a slimy scam site that stole my real ad then blurred the photos
Broken links to unrelated websites
Deleted email accounts
Disconnected phone number
Only one or two photos
The same photo listed all over country with no specific dates
The provider is too good looking to be true, offering everything you want for the cheapest price while taking your credit info for a deposit
Poor spelling and grammar with no or little written text
Sex-talk by email used to incite emotions to get your credit-card number
Fake Google search listings written by scammers also mislead people to pages that are not the same as listed on the search. Leave these sites immediately to save yourself grief. Take a look at the following FAKE Google listing that includes my old phone number with other providers:

adultlook.com is FAKE This link takes you to a scam site. You will not find my ad anywhere on this page and never will.
Here's a step-by-step example of how it's done
Let's start with this complaint a guy wrote about bait-and-switch action in my hometown Washington DC. You can see it for yourself on ripoffreport.com
Step 1
Don't believe the first thing you read. This is the first step because it is the most important.
Step 2
Check the links and phone number. I found the link to the Eros ad is no longer active, however the phone number has one viewable ad associated

Step 3
Go to the ad and read it for clues of being a Genuine Escort or Red Flag... as I did... and found the following red flags on the ad referenced in the rip-off-report:
Little information about the provider
No specific details about how to approach for a date, ie: appropriate times to call
No text or email options. Rememeber, genuine escorts want to be found by genuine clients.
There are probably more red flags I can find, but why waste my time? I already have four, including the glarring red warning from a guy online. This took me all of two (2) minutes to do this. Again, you can go to the scam ad and see for yourself. You many not have the same opinion. But this guy went to the trouble to warn people, and I must agree. I cannot prove anything. But if it was my money, I would hold onto my cash based on the red flags alone.

Avoid the scam site gfemonkey.com
I Googled my number and found fake ads with stolen content in the top three spots all associated with an unauthorized site. I have made several requests for them remove my content without response. The monkey uses a program called a photo ripper to steal ALL images from a site where I advertise, so many other providers are continually affected by this scam.
Once you involve yourself with these scammers there are lots of different ways they will try to hook your money deeper in ways that are too numerous to list here. If you pay attention to a few signs you will continue to get better at detecting scammers with time.
If you have been affected by a scam I'd like to hear about it in the comments section below. Exposing and sharing these experiences in a common community brings a good sense of a positive hobbying community.
