I would give her a try if she dropped her rates to £100-£120hr, I dont thinks she stupid enough to try blackmail for a second time and if she did how many years would she get banged up for for doing the same offence a second time.
I think with logan she had her 5 mins of fame with her glamour modeling (think she came 2nd in nuts mag comp a few yeares back)
and shes happy to try anything to get the next 5 mins.
Just keep your personal life to yourself in a punt, and unless she has the skills of MI5 she is not going to be albe to find fuck all about you.
