It might not be necessary. As I said, it depends in large part on how you source the companions. If I was going to see Rebaynia or Julia Sky I probably wouldn't worry about it (except for the screening. nobody gets that). If I was seeing someone new from LL or an indy MP then I definitely would. in other countries carrying decoy wallets or whatever isn't just a hobby precaution, but a normal travel precaution, for example. In any case, if you're going to limit yourself to MERB girls and reputable agencies then almost all of this is unnecessary, minus the screening stuff, which frankly, IMHO, you'd be nuts to give to anyone. Still, if you're cool with giving out the ID info and deposits and you're limiting yourself to the aforementioned then you probably have absolutely nothing to worry about except where your personal info goes. If you do decide to explore outside of the inner circle then you may want to consider appropriate precautions again going back to where you're sourcing from. 95% of the time it's all completely unnecessary, like having insurance on your car or home, but.......
