Some really poor banter lads my curiosity arose when I read some scams on here with WGs and girls stealing/blackmailing clients. I've even seen on twitter WGs openly talk about how they'd get money from clients by threatening to tell their wives.
That is blackmail, and covered perfectly well by the criminal law. The police usually pursue it enthusiastically as well.
Not if you change the terms, write the contract as a loan or as a non-disclosure.
Getting a prossie to sign an NDA?
And what are you going to do if she breaches it? Sue her for damages? Get an injunction? I suppose you could hire Carter Ruck for a few hundred K and get a super injunction, if you were a man of West8's means.
The best precaution is a good set of multi-layered security procedures which you adhere to strictly. Fake name, false background story, burner phone, never park within sight of her place, never, ever leave anything with ID lying around. That (plus several others which I won't talk about on open forum) is enough for me. A prossie would have more luck trying to blackmail Keyser fucking Söze.
The problem comes generally when you're a fluffy cunt who starts thinking the WG is your mate and telling her your life story. Unfortunately the ones who tend to be the most charming, beguiling and sympathetic are also the ones who are utter fucking bunny boilers.
