how confident can one be if provider has reviews on ter that they (the provider) is not LE just posing as a provider?

i've never seen a hot cop in my life. i'd say if she's really hot she's not a cop.

not LE.  Now that is not to say that it is impossible for a lady to get arrested and then flipped by LE to helping them, but that is a highly unlikely situation, and really a short term prospect due to boards like TER.

Play with ladies who verify you.  It may suck to have to go through verification, but a lady that verifies is much less likely to get busted.

Play with ladies that use verification sites...those sites serve both sides in this hobby.  They protect ladies, but also protect men by making sure members are aware of ladies that get busted.

There is a certain amount of risk inherent in this hobby...you hust have to do what you can to mitigate it.  See well reviewed ladies, never mention money, never mention anything specific about services (if if ain't in the reviews don't expect it), if you have a bad feeling...walk away, better to beg off and be safe than walk into a bust, and most of all, just be smart.

Best of luck to you, now get out there and have some fun....safe, smart fun, with a well reviewed lady until you are comfortable seeing ladies with fewer or no reviews.

Guys focus on LE...  but the risk of some scam is much greater...  unless you do your home work.  
Fortunately a lady with multiple reviews by reviewers with multiple reviews...  LE pretty much ruled out...  and no scams.  You need VIP to read the details to get an idea of what a lady offers...  the numbers are not enough.

your Mrs.

Find out what divorce court is like and you'll beg to be scammed and tossed in jail for an afternoon.

If your going to put your efforts anywhere, place them so you don't get busted by her.

nothing is "for sure" but for the most part if you PM some of the hobbyists that reviewed her you can tell if she's legit or not!
