I'm not so sure about this so I thought best to enquire on here.
I've been away with another girl on an international booking and to keep it simple she's horrible and she's a scam artist. The client may be too nice or placid to place a review of her. Can I warn other girls on here to not work with her?

Well if the punter who got a bad service is too wet to write an honest review then that's his problem and nothing to do with anybody else.

We don't allow third party warnings here unless there's concrete evidence of what happened and while the OP can post in Warnings if she herself was actually ripped off or scammed (rather than because she didn't like this other woman or disapproved of the way she works), bear in mind that we're not going to tolerate any stupid catfights if she decides to turn up and post her side of the story so it's not that likely any thread would last long before being locked .

Spoke to the punter today and he said he'll post an honest field report, I've also made him aware of websites that you cN review girls on.

She owes me money which she isn't going to give me. Does this count? I'm not intending to make this a cat fight even if she does come on here, I'm just being honest. I've never had a bad experience with another girl before till now. This girl shouldn't be working in my opinion. Should I post Screenshots of the WhatsApp messages I have off her and the client?

As far as I know screen shotting isn't allowed on here and as has been said it's not really your place to post conversations between this client and this lady.
If he wants to do this then he can do so on punters forums I would think.

I'm afraid you need to lick your wounds and move on.

Warning others is not a mantle for you to take on. If I tried to interfere with the business of other working girls who tried to fuck me over I'd gain nothing.

Karma is a wonderful thing.

What a good idea - it's the punters booking, he's the customer and he can sort it out. As for posting screenshots, you can't as the image facility has been disabled and by the sound of things it's just as well.

Since this is going nowhere, locked.
