I am a new hobbyist. I emailed a local provider that is very well reviewed on here, to get verified as I don't have references.

Here are some emails:

ME: emailed info about my employer and verification info...

HER:
Hi honey~
One quick, itty, bitty,  question---you'd wanna see me as a **(my occupation)**, not a deputy, right?    Just hafta make sure.....
____________________
ME:
I emailed back that I was not LE. (in a few more words than that, but talked nothing about services, etc...)
____________________
HER:
I hope you don't mind that I do my home work for my safety.  ***more explaining her background and concerns about safety*** I hope you understand my caution.  Oh, BTW--I'm gonna fuck with you allright........

I've screened you today. ***more about her screening***
So big guy, whenever the spirit moves you, take a look at the calendar on my website to check my availability and see what works with your schedule to see when we can rock!  ***more about scheduling a session***

That being said, the ball's in your court Sweetie!  When you do contact me, could you please use this email so I will kinda know where we're at?  My memory is shit, so this will help.  Thanks a bunch!

ME:
I definitely understand that, we both have a lot to lose.
I do want to be perfectly clear, however, that I am not soliciting you for anything other than the pleasure of your company. Anything beyond your time is not being requested or expected.
I will look at your calendar and mine to figure out what works. I will email you soon.
Again, I am not requesting anything other than time.
And... Thanks for your time thus far.

I am mainly concerned with the line in her second email that says "Oh, BTW--I'm gonna fuck with you allright........"
Would a provider say something like that in an email? Or is it possibly LE wanting to establish that I am seeking to pay for services?

Again, she is very well reviewed here, but possibly that doesn't mean anything?

Thanks for any help!

I would be VERY careful. She doesn't have to tell you she is a cop. I am a provider and I am very careful myself what I say over the phone or in email. Ask her if she would do nude pictures, a cop would never ruin her cover by pics

I think I would have left out the part about "I am not soliciting you...", but you should be alright if she is well reviewed.

All of this emailing reminds me why I like dealing with agencies though..just pick up the phone and go.

In spite of the "never talk about specific acts" rule, many, many ladies have been seemingly eager to get graphic in e-mails after they decided I was legit.

On a few occasions I have been in search of something very specific, so have (again, after screening) sent an e-mail asking permission to get specific.  Other times she (whoever "she" might be) will open the door with graphic comments via e-mail.

Short answer, if she is "well reviewed", and she has screened you well enough to decide you're okay, it isn't necessarily a alarm if things get a bit racy before you meet.  Not that it's the smartest move for either of you, but it does seem to happen with some regularity.

I personally don't see anything that would seem to be a red flag in the email exchange...
but I am not the one that will being going to the room or risking anything.

If it feels wrong to you, it feels wrong.
Go with your gut, because if things aren't right you are the only that is going to be paying for ignoring your gut feelings.

That said, I think your reassurance that you are "not soliciting" was more of a statement to make someone nervous than hers of "I am going to fuck with you alright".

"Fuck with" is generally a colloquialism meaning to mess with, clown, joke with, mock, etc. than a sexual act.

Also, she never mentioned a fee for "fucking with you" and she didn't list any activities...
had she written: "so, you want my full GFE menu including BBBJ and MSOG for $300/hr?" then yeah that would be putting a price on an activity but no mention of money and a colloquialism...not looking like an admission of anything.

Your reassurances though
(I do want to be perfectly clear, however, that I am not soliciting you for anything other than the pleasure of your company. Anything beyond your time is not being requested or expected. Again, I am not requesting anything other than time.),
made you look suspect, I would think.
it looks like you are trying too hard to reassure her...

As for her being well reviewed, do the reviewers have a number of reviews? have they been around sometime? A number of good reviews from unknown clients, where she is their only review or one of their only reviews does make a difference.

Been following your comments for a while now and find you intelligent and engaging. I wish you were in my city as I would love to have the pleasure of your company. I love seeing women, however it is a few and far between experience. Intelligence is a huge turn on and you have plenty of that.

I don't see any red flags but this is a lot of back & forth.  I really doubt that LE would go to this much trouble unless you are a high value target.  
LE wants to get you in the door, waste no time on screening, get you to actually say "$$ for sex" & slap the cuffs on you...  nice clean case with minimum effort.
Each provider has their own screening...  what ever makes them comfortable...  so it's hard to generalize.  If she has several reviews & at least some of the reviewers have several reviews, you can rely on that information.  You really do need VIP to read the reviews to get a good match...  I'm updating my bucket list & doing just this now.

I agree that if she is well reviewed and the reviewers have been around it is probably OK. My question goes to your first, and incomplete here, email.

Why is she asking about your occupation and not as a deputy. Either she is completely out to lunch (some providers are not the best on the business & scheduling side), or something in your email was maybe confusing to her.

i.e. you said you were a deputy comptroller...

Awww...you make me blush.
